So after trying everything to combat high IAT's with aftermarket CAI's (cai.. haha), and not wanted to spend more moolah on another close box CAI (like airaid) I decided to modify what I had. So his is what I did.. JLT elbow (shortened to right before the MAF housing), rubber coupler, stock 17 box, K&N drop in, removed the forward silencer, removed the charcoal filter, sanded & contoured the inside of the lid Works pretty fricken awesome. Always within 5c of ambient when cruising, idling today (27°c ambient, in never climbed above 36°c (97°f). That's just 9°c increase, awesome. Better than the conical air filter JLT CAI including 17 thousands different ways to keep the heat out. The plastic JLT tub was just to thin and heat soak was crazy, took forever to cool down once moving as well, likely cause the air coming in from the grill goes under the conical filter, hits the back of the box, goes up, then finds its way out the hood vent, gap between the JLT box and fender, etc,. etc. Raced a couple of my favorite targets last night, I'd say it's making more power. Quite a bit more actually. I'm thoroughly convinced it's the ELBOW that's responsible for making power, and the straight shot of airflow past the MAF from the stock lid, plus the K&N drop in is a proven 5-6 hp gain. Same tune, just redid the MAF scaling for the stock housing. So, lower IAT's, better throttle response, and at the much more horsepower than the stock setup. Follow me for more redneck recipes. Cheers.
