EX37 platform: built on Nissan FM platform (Front Midship) same as Infiniti G37 sedan/coupe (Batch 55 vaz513/vaz514 references), 350Z/370Z sports cars, Nissan Skyline (Japanese market). FM platform hallmarks: rear-wheel-drive or AWD architecture with V6 engine capability and modern multi-link suspension.
EX37 engine: 3.7L VQ37VHR V6 (~330 HP/270 lb-ft - famous Nissan VQ engine family 3.7L variant with VARIABLE VALVE LIFT - VHR designation for 'Variable Valve Event and Lift'). VQ engine family includes VQ25HR (G25 only Batch 57 vaz522), VQ35DE (G35 original Batch 57 vaz521), VQ35HR (EX35 Batch 59 vaz536), VQ37VHR (this engine), VR30DDTT (modern Q50/Q60 twin turbo).

Hubcap note: EX37 has ALLOY WHEELS as standard (not steel wheels requiring full hubcaps). 'Hubcap' terminology for modern luxury vehicles typically refers to CENTER CAP (small wheel center emblem cap covering hub/lug nuts), NOT full hubcap wheel covers. EX37 center cap features: Infiniti brand logo (embossed silver/black 'stylized mountain road' symbol), circular ~2-3 inch diameter, plastic ABS construction (some metal/chrome finish), snap-in mounting (3-6 plastic tabs), multiple style variations by wheel size (17/18/19-inch).
Common failure modes: (1) Missing/popped off (MOST COMMON - curb strikes, pothole impacts, car wash brushes, parking lot theft of premium logos), (2) Faded logo (UV exposure especially black/painted areas), (3) Cracked plastic (impact damage or age brittleness), (4) Broken mounting tabs (improper removal), (5) Faded chrome/metal finish. Replacement: very easy DIY ~5 minutes snap-in installation.

What is the Infiniti EX37?
Infiniti EX37 was BRIEF 1-YEAR PRODUCTION (2013 model year only) luxury crossover SUV: (1) Successor to Infiniti EX35 (2008-2012, 5-year production - Batch 59 vaz536 sister listing). (2) Engine change - EX35 used 3.5L VQ35HR V6, but for 2013 Infiniti upgraded to larger 3.7L VQ37VHR V6 (same engine as G37 sedan/coupe). Vehicle renamed 'EX37' to reflect new engine. (3) Brief 1-year production - only 2013 as EX37. After 2013, Infiniti rebranded entire lineup with Q-naming convention 2014+. (4) Renamed QX50 2014+ to align with new naming structure. (5) Platform - Nissan FM (Front Midship) same as G37 sedan/coupe (Batch 55 vaz513/vaz514), 350Z/370Z, Nissan Skyline. (6) Engine: 3.7L VQ37VHR V6 - 330 HP, 270 lb-ft, variable valve lift. (7) Transmission - 7-speed automatic only (Jatco JR710E). (8) Drivetrain - RWD or EX37x AWD (ATTESA E-TS). (9) Body - 4-door luxury crossover SUV ~182 inches. (10) Sister Nissan Skyline Crossover (Japanese market). (11) Competitors - BMW X3 35i, Mercedes GLK350, Audi Q5 3.2, Lexus RX350. (12) Used market - rare due to 1-year production. Often sold alongside QX50.
Why was 2013 EX37 only 1 year?
2013 EX37 production was BRIEF because of Infiniti's brand restructuring with Q-naming convention 2014+: (1) Pre-2014 naming: G35/G37 (sport sedan/coupe), M35/M37/M56 (mid-size), EX35/EX37 (compact crossover - this listing), FX35/FX45/FX50, JX35, QX56. (2) Q-naming 2014+: Q50 (replacing G37 sedan - Batch 55 vaz513), Q60 (replacing G37 coupe - Batch 55 vaz514), Q70 (replacing M37/M56), QX50 (replacing EX37 - this listing's successor), QX60 (replacing JX35), QX70 (replacing FX), QX80 (replacing QX56). (3) Naming logic: 'Q' for sedans/coupes, 'QX' for crossovers/SUVs, number indicates size. (4) Rationale: simplified identification, modernized brand image, aligned with Japanese 'Q' heritage, competitive with Mercedes/BMW/Audi. (5) Transition year 2013: EX35 had been 2008-2012 with 3.5L V6. Infiniti upgraded to 3.7L for 2013 (becoming EX37 briefly). 2014 - vehicle renamed QX50. Result: EX37 nameplate only 1 year. (6) Market confusion: many treat 2013 EX37 as identical to QX50 (which it essentially is). (7) For parts - many EX37 parts INTERCHANGE with QX50 2014-2017 (direct successor, same vehicle). (8) Collector interest - some EX37 enthusiasts value rare 1-year production status.
What is the Infiniti Q-Naming Convention?
Infiniti Q-naming was MAJOR BRAND RESTRUCTURING 2014: (1) Pre-2014: letters indicating vehicle type plus number for displacement or size - G (sport sedan/coupe), M (mid-size sedan), EX (compact crossover - this vehicle), FX (mid-size crossover), JX (7-seat), QX (full-size SUV). (2) Q-naming 2014+: sedans/coupes use 'Q' (Q50/Q60/Q70), crossovers/SUVs use 'QX' (QX30/QX50/QX60/QX70/QX80). Numbers indicate size hierarchy. (3) Rationale: simplified identification, aligned with luxury brand conventions (Mercedes C/E/S, BMW 3/5/7), modern brand identity, Japanese 'Q' letter significance. (4) Transition challenges: customer confusion, marketing material updates, dealer staff retraining. (5) Mixed reception: some praised modernization, others criticized as unnecessary - some critics said new names less memorable than G35/FX35. (6) Successor models: Q50 launched 2014 (Mercedes 2.0L turbo via Renault-Nissan-Mercedes alliance - Batch 55 vaz513), Q60 launched 2017, QX50 launched 2014 (direct EX37 continuation). (7) Q70 discontinued 2019. (8) Modern Infiniti continues today with Q50, Q60, all-new QX50 (2018+), QX55, QX60, QX80. (9) For this listing - EX37 was PRE-Q-naming vehicle (2013 only). Successor QX50 represents Q-naming transition.
Are EX37 hubcaps really center caps?
YES - Infiniti EX37 has alloy wheels so 'hubcap' typically means CENTER CAP: (1) Wheel types: steel wheels (economy) use FULL HUBCAPS (plastic covers), alloy wheels (luxury/modern) use CENTER CAPS only (small wheel center emblem). (2) EX37 wheels: ALL alloy (17-inch standard, 18/19-inch sport - no steel option). (3) What EX37 owners need when saying 'hubcap': wheel CENTER CAP (small cap covering hub/lug nuts), NOT full plastic hubcap wheel cover. (4) Center cap characteristics: small (2-3 inches), plastic ABS, Infiniti logo embossed, snap-in mounting (3-6 plastic tabs), hide hub and lug nuts. (5) Full hubcap (reference): large, covers entire wheel face, mimics alloy wheel appearance, common on Toyota Corolla/Honda Civic base trim - NOT used on EX37. (6) Terminology confusion: 'hubcap' loosely used. Technically incorrect for alloy wheel vehicles. (7) Aftermarket plastic hubcaps: some EX37 owners may add for different look or damage protection (rare for luxury). (8) For this listing - we sell EX37 CENTER CAPS primarily (OEM Infiniti from EX37 wheels, plastic ABS with logo, ~2-3 inches, snap-in). (9) Customer clarification - call (240) 301-0095 if uncertain.
How does EX37 relate to G37 and Q60?
EX37, G37, and Q60 are all Infiniti FM platform vehicles with VQ engine family: (1) FM platform sharing: EX37 2013 (this), G37 sedan 2008-2013, G37 coupe 2008-2015, Q50 2014+ (G37 sedan successor - Batch 55 vaz513), Q60 2017+ (G37 coupe successor - Batch 55 vaz514), M37/M56 2011-2013, FX37 2013, QX50 2014-2017 (EX37 successor), Nissan 350Z/370Z, Nissan Skyline. (2) VQ engine family: VQ35DE (G35 original - Batch 57 vaz521), VQ35HR (G35 late/EX35 - Batch 59 vaz536), VQ37VHR (variable valve lift - EX37/G37/M37/FX37/QX50/370Z/Skyline), VQ25HR (G25 only Batch 57 vaz522), VR30DDTT (modern Q50/Q60 twin turbo). (3) Vehicle type differences: EX37 4-door compact crossover SUV. G37 sedan 4-door sport sedan. G37 coupe/Q60 2-door sport coupe. 370Z 2-door sports car. (4) Body styles: EX37 taller crossover, G37 sedan lower sedan profile, G37 coupe/Q60 lowest sportiest. (5) Drivetrain: all FM platform available RWD or AWD (ATTESA E-TS). (6) Transmission: EX37 7-speed auto only, G37 sedan 7-speed auto only, G37 coupe 6-speed manual or 7-speed auto, Q60 7-speed auto. (7) Parts compatibility: engines INTERCHANGE (VQ37VHR), some transmission/drivetrain share, body panels DIFFERENT, wheels/center caps vehicle-specific. (8) For parts - EX37 center caps generally do NOT interchange with G37/Q60 despite platform sharing.
How do I install a center cap?
EX37 center cap installation is VERY EASY DIY (~5 minutes): (1) Tools: just hands typically, possibly thin flat tool to pry old cap, new center cap. (2) Prep: park flat surface, parking brake, don't need to remove wheel. (3) Remove old: locate in wheel center, pry off carefully from edge or push from behind through wheel center hole, watch for snap tabs releasing. (4) Inspect wheel center: verify clean, remove dirt/debris, check for damage, verify center hole size matches new cap. (5) Position new cap: hold facing outward, verify Infiniti logo orientation, note snap-in tabs on back. (6) Press in new cap: push into wheel center hole, apply even pressure across all snap tabs, should click/snap into place, don't force if doesn't fit (verify correct cap for wheel). (7) Verify secure: wiggle cap (should be firm), pull lightly (won't come off), all snap tabs engaged, sits flush with wheel surface. (8) Repeat for each wheel: 4 wheels total. (9) For full set: replace all 4 simultaneously for consistent appearance. (10) Cautions: don't drive at high speed with loose cap (will fly off), replace if loose before driving. (11) Professional installation not needed. (12) Periodic inspection: after car washes, pothole hits, curb strikes.
Why are center caps frequently missing?
Center caps frequently missing on Infiniti EX37 (and many vehicles) due to multiple causes: (1) Most common causes: curb strikes (friction pulls cap off), potholes (hard impacts eject), car washes (automatic brushes catch and pull), parking lot theft (premium caps stolen), aged plastic (mounting tabs brittle), improper installation. (2) Frequency: many vehicles missing 1+ caps within 5-10 years. High-traffic urban driving accelerates. Salt-belt worsens plastic degradation. (3) Contributing factors: snap-in design relies on plastic tab integrity, heat/cold cycles weaken plastic, UV brittles plastic, designs prioritize aesthetics over retention. (4) Theft considerations: premium luxury caps (Infiniti/BMW/Mercedes) often targeted, resale market exists, $30-100+ per cap motivates theft, easy to remove. (5) Driving with missing cap: NOT safety-critical (wheel/hub still secure), aesthetic issue only, some moisture exposure to hub, lug nuts visible. (6) Why replace: aesthetics, resale value, pride of ownership, hub protection. (7) Prevention: avoid curbs/potholes, cautious in automatic car washes, secure parking, protective wheel locks. (8) For EX37 - relatively easily lost: 17/18/19-inch alloy wheels (larger closer to curb impacts), premium logo attracts theft, luxury parking lot environments more theft-prone. (9) Replacement market: OEM $35-85 from dealers, aftermarket $20-50, used OE $20-50 (this listing). (10) For this listing - affordable used EX37 center caps from salvage donor vehicles, verified condition, cost-effective vs new OEM, easy 5-minute installation.
How does shipping work?
Free shipping all 50 US states. Infiniti EX37 center cap is small/lightweight (under 0.5 lb) shipped in protective box. UPS or FedEx Ground typical (3-7 days transit). Limited salvage donor pool due to brief 1-year EX37 production (2013 only), but extended significantly by: (a) Sister Nissan Skyline Crossover (Japanese market - same vehicle), (b) Successor Infiniti QX50 2014-2017 (direct continuation, same platform), (c) Predecessor Infiniti EX35 2008-2012 (Batch 59 vaz536 - some center cap sharing possible with verification). Customer must specify wheel size (17-inch standard, 18-inch sport, 19-inch optional - different center caps potentially), trim level, color preference (silver vs black logo), single cap or set of 4. Aftermarket Infiniti-style center caps widely available ($20-50) if used OE not preferred. NOS rare and premium-priced.
