Since I've seen lots of CAI posts lately I thought I'd post mine.
It'* a purolator filter for a 98 Chevy pickup. It will outflow any typical K&N filter. It'* crammed in the aluminum box with the PCM. I used a thin wall tube to apapt the filter to the hose that fits over the TB. I'm not totally happy with the hose, but I haven't found a good alternative yet. I originally was going to make a lexan cover, but lexan is a PITA to work with, so I made the cover out of aluminum. I like it better this way, no need to see the filter.
The car is an 87 Lesabre T-type with a 97 L67.
