The Acura ILX ran from 2013 through 2022 as Honda's compact executive entry under the Acura badge, built on the ninth-generation Civic platform but tuned with Acura's Amplitude Reactive dampers and a more rigid steering shaft for a noticeably sharper feel. Early cars came with a choice of a 2.0L four-cylinder, a 201-horsepower 2.4L four paired with a six-speed manual, or a 1.5L hybrid. The 2016 facelift simplified things: one engine, the 2.4L Earth Dreams direct-injected four mated to an eight-speed dual-clutch, and that powertrain carried the car through to the end of production in 2022. The 2019 refresh added the Diamond Pentagon grille and, on the A-Spec trim, 18-inch wheels and a sportier exterior package. The ILX's Civic roots mean a wide aftermarket parts base, and its FWD platform responds well to coilovers, air suspension, and aggressive wheel fitment. It's a clean, compact sedan that rewards intentional builds.
The 5x114.3 bolt pattern (5x4.5 imperial) is one of the most widely shared in the enthusiast world, appearing on the Honda Civic, Honda Accord, Toyota Camry, Mazda 3, Nissan Altima, Lexus IS300, and many others, so aftermarket wheel selection is deep and well-documented for this chassis.
On factory suspension the ILX already sits at a respectable ride height, and a set of aftermarket wheels and tires is enough to sharpen the look without touching the suspension. The stock setup supports 17- to 18-inch wheels with offsets running from a conservative +45 down to around +25, and the factory geometry keeps things clean. If you want to improve handling without changing ride height, suspension bracing and alignment components are available to tighten up the chassis response.
Lowering springs are the most straightforward drop for the ILX: bolt-in replacements for the factory springs that lower the car 1 to 1.5 inches on average, reduce body roll, and sharpen turn-in without the full complexity of a coilover install. The most popular setup our customers run on lowering springs is an 18x8.5 +35 wheel with a 225/40R18 tire, and it almost always bolts on clean with no rubbing reported. Springs pair with your existing struts or can be matched with performance struts for a more complete setup.
Coilovers are where the ILX build gets serious. Height-adjustable coilover kits let you dial in the exact drop you want, from a mild street drop to an aggressive low stance, and damping-adjustable units let you tune the ride for daily driving or weekend spirited use. Our customers running coilovers most often go with an 18x8.5 +35 on a 225/40R18, and most bolt on clean, though some need minor liner trimming. Stepping up to an 18x8.5 +38 on a 235/40R18 is a real mixed bag: some bolt on clean, plenty need a trim, and a few go further. Coilovers open the offset window wider too, with builders running anywhere from +22 to +38 depending on how aggressive they want the stance.
Air suspension is the top of the ILX stance game. A full air management kit lets you raise the car for daily driving and drop it to the ground for shows and meets, with the ability to fine-tune each corner independently. Our customers on air most often run 18x9.5 wheels at offsets from +15 to +40, with the typical setup landing around +25, paired with 215/35R18 or 225/35R18 tires. Most bolt on clean with minor trimming at the aggressive end. The boldest documented build in our community runs an 18x9.5 +22 on 215/35R18 on full air, a setup that shows what this platform can do when you commit to the stance.
The ILX's 2.4L direct-injected four-cylinder responds well to improved induction. A cold air intake replaces the restrictive factory airbox with a larger-diameter tube and a high-flow filter, pulling cooler, denser air from outside the engine bay. The result is sharper throttle response and a more pronounced induction sound under hard acceleration. Drop-in high-flow air filter replacements are also available for a simpler upgrade that improves flow without relocating the intake tract.
The 2.4L DCT ILX has a clean, rev-happy character that a cat-back exhaust system brings out. A cat-back replaces everything downstream of the catalytic converter, leaving the cat itself in place, and opens up the exhaust note from the factory-muted tone to something more present and sporty. Flow improvements behind the cat also let the engine breathe more freely at higher RPM. Mid-pipe options are also available for builders who want to address the section between the cat and the rear section specifically.
Beyond intake and exhaust, the ILX platform supports a solid range of engine and drivetrain bolt-ons. Valve train components, ignition upgrades including coil packs and spark plugs, and throttle body upgrades all contribute to a more responsive engine. For the manual-transmission cars from the 2013-2015 era, clutch kits, flywheels, and throwout bearings are available to sharpen the drivetrain feel. An oil catch can is worth considering on the direct-injected 2.4L, intercepting oil vapor in the PCV system before it can deposit on the intake valves, a documented long-term concern on DI engines. A supporting ECU tune gets the most out of a combined intake and exhaust setup.
The ILX's clean sedan lines and Acura's Jewel Eye LED headlight design (standard from 2016) give the car a strong visual foundation, and the right lighting and exterior upgrades sharpen that character into something intentional.
Headlight upgrades are a natural starting point: projector and halo retrofit kits give pre-2016 ILX owners the modern LED look, while sequential LED turn signals and DRL accent lighting add motion and presence to any year. Tail light upgrades with LED elements and sequential signals tie the rear end together. For the show and stance crowd, underglow and interior ambient LED lighting are popular additions that show off the car's low setup at night. Fog light upgrades and replacement bulbs across the interior and exterior round out the lighting palette.
On the exterior, paint protection film and clear bra coverage keep the ILX's body panels clean, especially important on a car that sits low and sees road debris up close. Body accent pieces and exterior styling accessories let owners personalize the look beyond the factory A-Spec package. Windshield and window upgrades are available for those who want to address visibility or privacy. For towing, a small hitch option exists for light-duty use.
Inside, the ILX benefits from quality floor liners and cargo protection to keep the interior clean through daily use. Seat covers protect the factory leather or cloth, and interior LED lighting upgrades brighten the cabin. A steering wheel upgrade is available for those who want a more driver-focused feel at the helm.

Good: Clean, daily-driven improvement over stock, sharp and intentional without drawing attention for the wrong reasons. Better: Noticeable street presence, a car that sits right and turns heads at a light without sacrificing everyday usability. Best: Show-stance intent, built to be seen, the kind of ILX that stops people at a meet and makes them ask what it's on.
It depends on your goal. If stance and fitment are the priority, suspension and wheels are the natural entry point: lowering springs or coilovers change how the car sits, and the right wheel and tire combo locks in the look. If you want more engagement from the drivetrain, intake and exhaust bolt-ons are a clean starting point that don't require suspension work. Most builders have a clear goal in mind, and the best starting point is the category that moves the needle most for that goal.
Yes. Get pre-approved before you start building your cart so you know your budget going in. Pre-approval is fast and doesn't require you to have a specific order ready. Once you know what you're approved for, you can build out the full setup, wheels and tires, suspension, performance, and accessories, and check out with confidence. Pay over time on a build that would otherwise require waiting.
Our fitment team knows the ILX platform and can answer specific questions about offset clearance at a given drop, what trims, and what combinations need minor liner trimming versus what bolts on clean. For install questions, whether it's coilover setup, air management routing, or brake hardware, our team can walk you through what to expect. Real builds from our community on the same platform are also available in Our Gallery for reference.
We back every fitment recommendation with real data from actual ILX builds in Our Gallery, not guesswork. The 5x114.3 bolt pattern opens up a wide aftermarket wheel selection, and we carry verified fitment options across that entire range. Beyond wheels and tires, we carry coilovers, air suspension, brakes, performance bolt-ons, and interior and exterior accessories, all confirmed to fit this platform. One source, verified fitment, real community proof.
