Which one ??
The CAI one or the one that sits next the engine ??
I have the CAI one, you need to remove the front bumper to fit it and also replace the washer bottle with the Injen one, quite easy.
Just one bit of advice, read the fitting instructions first :idea:

BTW, hope you ordered from clubrsx, I got my CAI here including Tax and express del for £220.
