Well after much research I went for the SPEC BMW N54 SPEC-Design Single Mass Flywheels (8-Bolt) / Aluminium × 1 and the SPEC BMW N54 SPEC-Design Clutches Stage 3 from ML performance. The stage 3 clutch allows for up to 570 lbs, which is reassuring. Just need to find a reputable fitter now.....hahahah

Thanks for the advice Dave. I will take a peek at some twin plated upgrades.

Hi all My 135i has had a new downpipe and intercooler, and is now making 386BHP and 403ibs/foot, and I want to upgrade the clutch. My longer term plans are to get the care to around 450bhp. Any advice on best performance cltches? cheers

I got a tyres on the drive guy to do it. All tyres have 39PSI in, as done yesterday. I will look on youtube for the reset sequence. thanks

Hi I have a 2009 BMW 135i. I got a puncture which was fixed. The thing is though, the puncture warning symbol is still on. I've checked all tyres and they are all good. Any clues? cheers Nick

Not true, i had a downpipe and uprated intercooler for my 135i and got an extra 80BHP and 108 lbs. Injectors wont be affected.

Which article was it Dave?

Hi I am new here. I bought a used BMW in August 2020 and thought I would have some fun with the N54 engine. So, I got a CSF Intercooler and a Wagner downpipe fitted. With a remap and dyno I got 386BHP and 403lbs. I am very happy with this result, but was wondering how I can get more gains without spending £10000+??

Thanks Dave, I have opted for a downpipe. I know this is more hassle for the MOT time. But, after extensive research, this seems the more 'fun' option.

Hi guys, I have just purchased a 2009 BMW 135i N54 and want to mod her for more power. I have sourced a performance intercooler, but cannot for the life of me locate a N54 performance cat from a UK dealer! (I don't want a cat less pipe, cos of the MOT). Has anyone else have these issues, or will the N55 fit the N54? cheers
