K&N idle dip
I have a K&N intake (not my first choice but it came with the car.) Personally I dont think it looks good and the design looks more of a warm air intake then a cold air since the box is hardly sealed.
However, i dont have the stock and dont feel its worth wasting a $300 intake setup just because of the idle dip i have.
I know there is a TSB on the idle dip but Subaru states that the "tech verified high idle due to K&N cone filter". I think this is bull as the system should be able to learn the subtle intake improvements but they refused to reflash the system to fix the idle dip.
So my question for you guys is: should a new intake cause the dip/high rpm?I'm seeing the 750rpm drop to 500 then back, sometimes reaching 1000 for a short while. Or are they full of crap and just trying to get out of doing the work? I've already had it with this dealership and plan on going to a different one if I have to.
Thanks,
