What performance accessories are available?
Dinan has both software, exhausts and cold-air intakes (CAI) available for the 323 and 328. In addition, Dinan has software for the steptronic trannys. This software reduces the shift lag when using the manual mode and drops to 1st gear when stopped. Jim Conforti will have both CAI and software available soon (been forever.). One major advantage to Jim C’s software that it can be reversible, meaning that an owner can install or remove the software returning the car to stock programming. Currently, only Dinan has software and CAI for the 330’s in production. ECIS now has CAI systems available for 323s, 325s, 328s, and 330s. Check out www.dinanbmw.com, www.ecisbmw.com and www.sharkinjector.com for the latest info and details. There are also a few supercharger manufacturers for the 323/328’s but have not been popular due to the extra stress put on the engine and lack of warranty coverage.
