I was looking at the stock air box in my car and noticed a big gap in the foam that is supposed to seal the front snorkel into the air box. I'm wondering if that could be some of the reason that the fuel trim's go so far out of wack with my K&N drop in installed . Has anyone tried just removing the snorkel all together ? The opening into the airbox is larger than the snorkel so i would imaging it would flow a good amount more air .

 

Part of the air box mod is to remove the snorkel. The K&N only changed my LTFT's a point or two when I ran it.

It flows much better at the high end.

 

Oh I see. I was reading a thread where they cut the snorkel at the bend and put it back on with a coupler. I'm going to try it with just the snorkel removed and see what happens. I know it will be pulling in warmer air but with the temps here already in the 50's during the day ....it won't make that much of a difference. Thanks for the reply.

 

I ran mine that way until I got a silicone coupler to put the venturi back on it, no issues. Some have just jammed the venturi back into the snout on the airbox. Intake temp difference was minimal with or without the venturi on it. Theoretically, the venturi should help but the logged difference in airflow was minimal, if any.

I just compared the stock MAF table to my K&N air box mod one and I had about 6% dialed in the LTFT's so it shifted it more than I remembered. Sorry for the earlier misinfo.
