I apologize in advance if this is a re-post. I decided to take out/clean the stock air assemblies only to discover that the airboxes looked the same as my backyard with leaves and crap saturating both boxes. I took them out completely and washed them in and out. Then I got a bit curious when I saw what appeared to be a baffle on both of the intake pipes. At first I didn't want to open them up as they were slightly glued but then I figured I'll be getting a CAI soon enough so what the heck. I popped one up and sure enough it was a pretty aggressive baffle built in. Looking at the design it definitely disrupts the airflow and possibly limits it somewhat, of course it seems very effective at cancelling the noise. I was about to take my dremel to it but I was somewhat time limited and figured that I can just line the inside of the intake pipe where the holes are with aluminum foil tape so the air would flow straight through. At the same time I removed the front/rear hood insulation weather strips, my hood insulation blanket was already off. Took it out for a spin and holy crap the supercharger whine/intake sound got wayyyy louder, I mean wow sounds awesome.. way louder than with just the diy 'code 3' mod that I did earlier. Throttle response might be a tad better too, but I won't really comment on that. I would be curious what the sound difference would be with no code 3 mod and just the sealed off baffles in terms of how much whine could be heard. Here are some pics for reference.

Fram oil filter

 

did that airbox mod 3 yrs ago. added 3" tubing and no inc in hp on the dyno. not sure i think they are high tech coolers that cool the massive hot heat that comes in from outside the car
btw thats an oil filter

 

I'm glad to see you getting familiar with the car and using a good fleece oil filter.

Oil filter? Really... I was trying to see what type of Walmart special the filter was.

 

I like Corgi's.....adding one to my collection...black of course......her name is Gabby...like me...

 

Congrats! They are seriously the best dogs ever, super smart, friendly, loyal, playful. I got mine when he was 8 weeks old and attached is an understatement .

I think that is a cheap Chinese filter like these quick oil change guys fit. I had one in my car when I got it and it too had warped and was loose on the filter holder.

I think the Fram number is CH8902 for the better one, the cheap one also starts with a CH.

PS
The Frams look like the OEM filters.
