Annoyingly the filter didn't get installed, turns out they didn't ship the Venturi insert pre-installed into the intake tube, so when I started the car the rev's were erratic and they kept rising without the accelerator. So I told them to replace the stock filter, but the sound symposer wasn't re-attached, the pipe was just blocked up
Really not a idea to mess with the intake on this car, the stock intake is excellent for sound and performance, there is really no need to change it.
Plus fitting an intake on this car there are only a handful which are safe without a tune which are Air Raid, Roush and Steeda making sure you leave the insert in the maf area. Stock tube diameter is 85mm and you must strictly stay at this. A lot of CAI intake have larger MAF tube areas of 100-115mm at which point the car MUST have a remap designed for that specific intake to run correct and even then the gains are 5-12BHP on a dyno, on the road you can even lose power due to heatsoak as the stock setup is a true CAI whereas the Roush and Steeda are not, Air Raid is however.
Keep stock intake my advice and just throw a panel filter in there.
If you want more performance get a tune/remap as they are good on this car for 25-40BHP peak with around 40-60HP/Torque gains in mid-range, really very noticeable.
