Hey guys I appologize if this is stated somewhere else but I searched all over and could not find it. I have a dcrh with full greddy exhaust and of course have the check engine light on now. I want to pick up a defouler until I can afford the kpro.

My question is which one is better to get, the straight one, or the angled defouler. If anyone can help please let me know I need to get one ASAP.

better yet, make one yourself! costs like 7 bucks or less.

use the HELP! spark plug nonfoulers. drill one out (i think 1/2"), screw the other one on the drilled out one, put your seconday o2 sensor on that combo, and put it on the cat. reset your ecu by pulling the fuse, do the idle relearn procedure, and voila! dunzo!

Great thanks. What is the idle relearn procedure?

It's in the owner's manual. Pull the ECU fuse for 10-20 seconds to clear its memory, then do the procedure:

-Turn off all electrical items (A/C, radio, etc.).
-Start the car, and hold it at 3k RPMs in neutral until the radiator fan comes on or the coolant reaches 194F.
-Let the engine idle for 5 minutes with the throttle fully closed. If the radiator fan comes on, do not include its running time in the 5 minutes.
