How to Make a cone intake on your 4cyl
- 3" inner diameter opening cone filter
- pre-cut 2 1/2" exaust pipe piece, about 3" or 4" in length (sells in any automotive store)
- a pair of pliers
- wrench with flat head screwdriver attachment (or flat head screwdriver will do)
How To Do It
Undo the 2 wingnuts that holds the air box cover (which is on top of the engine) and remove the air box cover.
Remove the stock air filter, look closely in the airbox, you'll notice there's a big piece of metal kind of covering the big rectangular hole out to the stock hose, bend this metal with a pair of pliers downward towards the throttlebody and injector so that it isnt restricting the air flow.
Put back the cover and put the wing nuts back on, but this time tighten down the wing nuts with the same pair of pliers, you want to tighten this down so that there are no vacuum leaks.
Now take the pre-cut exaust pipe piece, attach the cone filter on one end, tighten it down real good with the flat head screwdriver.
Okay, now here comes the fun part, follow the airbox and the stock rubber hose down to where it ends at the front you'll notice there's a little attachment that looks like a vacuum attachment of some sort, lol, this is a metal attachment held on with a pipe clamp, loosen the pipe clamp, now, this attachment is also held on with two bolts onto the chassis, remove the two bolts and carefully remove the attachment, as you dont want to rip the rubber hose.
Attach the other end of the pre-cut exaust pipe to the end of the rubber stock hose and tighten down real tight. The filter should rest on top of a rad hose right beside the battery.
