I have decided to replace the stock intake(Old and Busted) on my 79 N/A with a cold air setup, if for no other reason than to clean up the front end of the car, and hopefully unrestrict the breathing. This is where I turn to you guys, do you have any input on what the current best brand is? Do they make a setup specifically for a ZX, and if not, what fits?
I like the APEXi PowerFilter, but can't find them except for on Ebay.
No clue lol, but the point of my post wasnt directions to make your own it was suggesting that you can build your own for cheaper and it will be just as effective. Use whatever size piping is easiest for you
then get an Apexi power intake filter to stick on the end. Its a dry type so you don't have to keep oiling it and the oil damaging your AFM. And you'll get a similar increase in horsepower compared to K&N.
i simply removed my stock air intake, and bolted a little pod filter on the end, picked it up for $30AU ($20?US) at autobarn. I dont see why people would need to get custom pipes made up on a ZX, my filter fits perfect
Oil from an air filter isn't going to damage a gate type AFM, it's the hot wire types you read about having this problem.
BTW the factory air box -is- a "cold air intake", look at where it pulls air from. Unless you have a ported intake with a big TB, those cold air intakes aren't going to make any power, although the extra noise will make you think it's faster!

You're saying that box around the intake doesnt restrict the airflow AT ALL?
Do you connect the 90 degree bent pipe directly to the AFM, or do you use the stock rubber elbow that connects to the AFM? It seems that if you connected directly to the AFM, the bend would have to be less than 90 degrees since the AFM is already angled where it's mounted.
