i think its CPI, so K&N makes a specialized CAI for it, runs around $250 or so. it would be cheaper to make your own, and not as hard, but easier to just buy one. they really dont increase power, and i didnt get any gains in mpg, but they make throttle response a lot faster and smoother, and that was worth it to me.
There really is no cold air intake for our trucks. A cold air intake is an intake that has the air filter outside the engine compartment. I have seen companies try and pass off thiers as a cold air but it isnt. Some companies offer a heat sheild and say they are cold air. They arent. For a couple reasons.
1. Most trucks are used for work or get into the dirt a lot more often than your average passenger car.
2. You would have to do some cutting to run a 3 inch tube outside of the engine bay. Most people dont want to do that.
my intake works the best bye far . I have a stock box w/ the bottom completely cut out with a drop in k&n filter.Also I cut out the firewall so my filter is actually 3/4" away from the direct outside air. Its like a vacuum. Plus!!! the stock box works as a great heat shield
I had a k/n Cone it sucks.... If you feel the filter after a drive, it is melting hot. Just like the top of my stock box, but the air coming in my truck is almost completely outside air, rather then 75% hot air and 25% of some worthless cold air that is allowed in naturally.
The Intake I made actually lets the filter sit right in front of the headlight and turn signal. All the way down in the pocket. Although the drop in filters are great I have one in my Tahoe and Turbo Beetle. But the wife doesnt drive the S-10 so I can do whatever. I may cut a 3 inch hole right there at the bottum and build a real cold air intake tube with the filter "Outside" the engine compartment
I just think that that stock box deflects/absorbs alot of the heat. I believe the hole coming ito the stock box is 3" so im already getting cold air but the shape of the box os what creates that vaccum rather then just a 3" hole outside the engine compartment.
By all means. I would bet that your stock box set up with the bottum cut out probably allows close to the same hp as an aftermarket intake no doubt about it. I just didnt want to cut up my factory parts is all
