I've decided to dump my HKS filter and go with the highly touted Apexi filter. Do you need a retune if you're just swapping air filters? (I'm still using the HKS pipe) I'm already tuned for my intake but I figured I'd just double check...

 

im thinking about doing this too, where did u get the apexi filter from and was it just an easy swap?

 

Well I bought it used off a member on here. It's still in excellent condition though and at the price I said what the hell, I may as well do the swap. I haven't actually swapped the filters yet but from what I've read the Apexi fits perfectly on the HKS pipe. I just want to make sure that I can switch filters without messing up my tune.

 

no. since your car already has a tune that is ready for more air than stock you are fine. no re-tune needed

 

no. you do not need a re-tune. once your computer is tuned for an air-intake, its always going to be tuned unless you take the tune out. you will be fine with the apexi filter.

 

Awesome, thanks for the replies guys.
