BMW 3 E93 Parts

The BMW 3 Series E93 convertible holds a genuinely special place in the Bimmer world. Built from 2007 to 2013, it was the last 3 Series to wear a fabric soft-top - a deliberate nod to driving purity at a time when every competitor was chasing retractable hardtops. What you get is a lighter, more communicative chassis that still communicates every nuance of the road through your hands and seat. Pair that with BMW's legendary rear-wheel-drive balance and a lineup of engines that range from genuinely capable to flat-out tuneable, and you've got a platform that rewards the enthusiast who actually pays attention.

The E93 shares its platform with the E90 sedan and E92 coupe, which is great news for parts availability and community knowledge. Almost everything in the Suspension catalog crosses over, and the aftermarket support for this generation is deep. Whether you're tracking down a clean 328i as a weekend toy or already own an N54-powered 335i and want to extract serious power, the E93 deserves more credit than it typically gets on the forums.

Engine-wise, the lineup is straightforward but significant. The 328i runs the naturally aspirated N51 or N52 inline-six - smooth, reliable, and a solid foundation for bolt-ons and a proper Exhaust upgrade. It won't embarrass itself on a canyon road. But the real conversation starts with the 335i and its twin-turbocharged N54. If you've spent any time in the N54 crowd, you already know: this engine responds to tuning the way most BMWs simply don't. Stage 1 tunes on stock hardware push 370–380 whp without breaking a sweat. Add upgraded charge pipes, a downpipe, and a flash from Bootmod3 or MHD, and you're deep into territory that makes track-day regulars take notice. There's also the M3-adjacent crowd running the S65 V8 in the E92, but E93 M3 production was limited in the US - if you've got one, you know exactly what you have.

No platform is perfect, and the E93 has its homework assignments. On the N52 and N51, the valve cover gasket and oil filter housing gasket are nearly guaranteed jobs by 80,000 miles - do them together, do them once, move on. The electric water pump and thermostat are also consumables on a long enough timeline; budget for them and don't cheap out on parts. Cooling system maintenance is not optional on any of these inline-six engines.

The N54 has its own checklist. Charge pipe failure is a when, not an if - the OEM plastic couplers crack under boost, and upgrading to silicone replacements from a brand like Turner Motorsport or ARM Motorsport should happen before you tune, not after. High-pressure fuel pump (HPFP) issues plagued early cars, though BMW's extended warranty coverage addressed many of those claims. If yours hasn't been done, inspect it. Walnut blasting the intake valves every 40,000–50,000 miles is mandatory on direct-injected engines - skip it and you'll feel the carbon buildup in throttle response and cold-start behavior. Browse our Engine section for everything from gasket kits to upgraded fuel system components.

On the chassis side, the E93's soft-top mechanism is generally reliable but does require periodic attention to drain tubes and weatherstripping. Structurally, convertibles flex more than coupes, so if you're planning aggressive suspension work, a quality strut brace and subframe reinforcement are worth considering before you throw money at coilovers. Speaking of which - the stock suspension is competent but soft for anything spirited. A set of coilovers from KW, Bilstein, or H&R transforms the car without sacrificing the daily-driver compliance that makes the E93 genuinely livable. Check out the full Suspension catalog to see what fits your build goals.

If the E93 is your everyday car, keep it comfortable and reliable. Prioritize maintenance upgrades first - cooling system, charge pipes if you're on the N54, fresh fluids. Then layer in quality-of-life improvements: a proper exhaust note from a cat-back by Remus or Eisenmann (see our full Exhaust lineup), a stage 1 tune, and a wheel and tire package that fills those arches properly. A set of staggered 18s or 19s on a quality square setup from Enkei or BBS makes the E93 look intentional without going full show car. Browse Wheels & Tires for fitment-verified options.

For the track-focused build, the conversation shifts. Stiffer coilovers, upgraded brake pads and fluid, a limited-slip differential if you don't already have one, and a serious tune with supporting mods become the priority stack. The E93's added weight versus the E92 coupe is a real consideration for lap times, but it's not disqualifying - plenty of convertible Bimmers have embarrassed hardtop cars at the local HPDE because the driver and setup were dialed in. Aero options are more limited than on the E92, but a subtle front lip and trunk spoiler from our Body & Aero section clean up the look and add just enough downforce to matter at speed.

The E93 is a platform that rewards investment and attention. Buy the right one, maintain it properly, and mod with intent - and you'll have a Bimmer that puts a grin on your face every single time the top goes down.
