alright guys just got around to doing my stealth CAi.
I went to autozone and looked for a k&n filter with the 3 1/4 diameter but was not there.
so like many i bought the spectre filter that gives you the options of 3, 3 1/2, & 4".
took about 40 minutes following this guide
so, what to expect once done?
Rough idle for at least 10 minutes.
Make sure that everything is reconnected and tightened properly.
don't worry when it's idling because it will sound rough, just give it time.
i can tell my exhaust sounds a little deeper and overall response is better.
nice 25$ mod. :)

would definitely consider it "stealth" from top engine view you can't even tell ^-^ haha.
