I dont feel like writing a full how-to on it right now (hence the reason i didnt put it into the how-to section), but i will give you all the information...
first off here is the parts list:
APC Intimidator Air intake
-universal part #:151011k
-Honda Civic/ Crx 88-91
Spectre Performance Couplers
-3" to 2.5" reducer
- 4" long 3" diameter coupler
now more info on those parts:
The APC Air intake comes with filter and one single length of pipe. also there will be a cheap plastic coupler and crank case hose (trash those pieces) but there will also be some strips of metal that you will need to bend to make a bracket. The kit should be around $60. You can order all the parts from summitracing.com for the cheapest I have found. Search for the universal part number for the air intake and then search for spectre under the air and fuel delievery section. You need one of each coupler.
You are going to have to cut the pipe and flip a piece around to get it to fit right. I will try to find pictures that show where and how to do this to post up later...along with the directions i give with the kit but i have to load the pictures on to cardomain first (which takes so long with dialup)...but this should suffice for now
