I have a question for whom ever know's. What, if any, is the real difference between the airaid and k&n air intakes, or other brands? I had k&n in my old truck but to me they look pretty much the same. Is the k&n cotton and wire mesh filter any better than the airaid?

 

I have no experience with Airaid, but I know K&N is a high quality product.

I have a question on the same subject...Is there a final verdict on the whole intake kit/check engine light issue? I read last night that Airaid claims the only reason a check engine light would come on is if the kit is not sealed properly on the TB. Others will tell you the computer throws a code based on a lean condition resulting from too much airflow. I find the latter hard to believe, but I dont even try to use common sense to wade through modern EFI systems.

Also, since there is not a K&N kit available yet for the 5.4, are there any other readily available alternatives to the Airaid? I would like to buy a kit, but I am not enthused with the look of the Airaid kit, nor do I want to spend $300 for my check engine light to come on for the first time after 8200 mi.

Sorry I'm so long winded, damn engineers!...thanks for any help on these subjects!!

I'm not sure on the trucks.

I do know on mustangs with these type of filters, if there is too much oil on the filter it will get on the wires for the mass air meter and cause the same type of problem.
Hope this helps!

 

I have the airaid installed and no check engine light. The intakes are pretty simple, so I cant see there being any real difference between the two.

 

So how much should we expect to pay for an airaid system

 

I have a airaid on my truck the check engine light came on, I disconnected the battery and cleaned the mass air flow sensor with Berrymans electronic cleaner, that was about 4,000 miles ago and no problem.
