gjm 3258 Report post Posted March 8, 2018 Originally bought for Mrs M's 320i coupe when we were back in the UK, so more than 5 years ago. Never fitted or used. @charles28 was getting one (see thread linked below) - I've not dug further to see what results he got, but when I bought it from E30Zone, there were good reports. OK - not going to turn a 320i (or 520i) into S54 killer, but it does enhance what you've got. (Be sure to service your car correctly, and use good fuel.) Price was ~$75 back then; how does $50 sound for a sensible improvement? See here for previous thread: Quote Share this post Link to post Share on other sites
