3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I currently have a Dinan package on my 323Ci which includes software,
exhaust & C.A.I., & brings it up to about 190 hp. It cost me about $1700 with labor charges.
To get more than that , you may want to check out Jim Conforti's products, including his Shark Injector, but I doubt you'll get over 200. The best really noticeable upgrade would be a supercharger, which you can get from any number of aftermarket companies (Dinan, E.S.S., etc.). But look to spend upwards of $5000 plus labor.
the home made ebay intakes are trash..dont go for them
gruppeM is very pricy...for the same performance, ecis intakes are prob half the price yet yield to same performance numbers. But gruppeM has the pimp look (carbon fiber and stuff..very very attractive) Both are easy to install. My gruppeM took 10 mins! No seriously, it took me 10 mins, in the dark, during one winter night. Intakes like the DINAN and i think benfer requires the bumper to be removed whereas the gruppeM and i believe ECIS does not require that.
GruppeM is about $500, ecis is about half.
sound wise, majority says GruppeM has the sexiest sound out of all the intakes available for the E46.
any intake will generally give you better throttle response, increase performance numbers, and better sound.
im a happy GruppeM customer. very very happY!
shark injector reprograms the ECU in your car. one of the best, if not THE best software available. Technik software is also good. shark injector is about $350.
soo many exhausts out there i cant really list them all. from the top of my head, i recommend remus, borla, and supersprint. expect to pay in the ranges from $300-800.
