Afta-Maf + K&N drop in review

Well seeing as Subaru dropped the SPT CAI and I was to scared to go with a non Subaru approved brand (untuned).
I decided to go with a Perrin Afta-Maf along with a K&N drop in. I did both at the same time so I can't break
up the review. I had few K&N drop in's before on non turbo cars and I can say I never noticed a bit of difference
after installing them. However, with this set up It does appear to make the car breath easier. I did notice an improved throttle response and ever so slightly more sound from the BOV. I'm hoping to get a few more MPG out of it as well but
time will tell.

I have had this set up since I have owned the car and love it.. You can hear the BPV more especally on cold mornings.. but As for a a different feeling I dont know they have been on since day one so I have no imput on that..

Perrin did a write up on this as well and yup you should definitely have the improvements you mentioned. I think the netted a 3-5whp increase with added throttle response as well.

Glad ur happy :)

It's gonna take a while to find in Nasioc so if any of you remember where it is please post.
I think the topic started out with foam vs cotton and other oil less air filters.

I will search for it again when I have time.

I got the PErrin tube during the T-day 10% offering.
Picked up the K&N filter as I already have a cleaning kit for it and its the filter that the XPT OS tune specifically was tuned around.
Total was $70.
