Hmm.. I think I'll try and replace the CAI to the stock air filter in the next few days.. see how that goes..

As with the mods, yeah I thought it was O.K as I have very minor mods for my car without tune etc. and they're all very easily replaceable with the stock parts.. that's why I didn't think too much into it.

Thanks for the response
