Re: Induction advice- would this work?
the air filter is little here or there, its the intake pipe - the true induction side - that really counts.
Having messed about with bits of metal and silicone pipe, and also tried the gsr kit amonst others, I can honestly say its not worth mucking about trying to DIY a decent intake system, nor is it cost effective.
Having tried all this, you are much better buying the GSr intake/induction pipe and using his air filter as well, this chap has spent too many hours fine tuning and testing his stuff, he only manufactures what works and provides a geniune bhp increase, and even the best of efforts elsewhere do not seem to measurfe up in terms of performance and often the costs spiral way above that of the GSR system.
Thats my 10pence worth anyway!
