this might be a stupid question, but i have never installed a CAI. anyways i was looking at my stock intake (07' 4.6) and there are two wires connected to the intake.

if i install a K&N CAI for my 4.6 should there be connections for there wires? if anyone has recently done an install maybe you can help,thanks!

 

Hello, yes the K&N kit has the connectors for the wires included. It looks very complicated but if you follow the instructions it is very easy to install. The only thing is you must have a tune for it, very importent. My pick was the SCT tuner with VMP tunes. Never threw a code and it sounds really good. What a difference in performance.

 

i wasn't aware i also needed to tune it. what would happen if i just installed it and didn't tune it?

 

I don't think you'll need a tune, due to the fact of having the 4.6. The 5.4's were noted for running lean from the factory. Adding a CAI would push them over the edge. The worst years for the 5.4 were the 04-06, i believe.

 

I'm in agreement with the above post. I'm thinking you'll be fine.

 

when i brought my truck in i was talking to one of the mechanics and told him i wanted to add the CAI and he never mentioned anything about getting the truck tuned.

 

You DON'T have to get it tuned. The 4.6 is fine...Altho a tune from a reputable company will take advantage of the increase in airflow the CAI provides.

 

Yes all the above replies are correct, sorry I didnt pay attention to your 4.6 description.please disregard my post because I was talking about the 5.4

 

and even the 3 inch intakes and smaller on the 5.4 dont NEED a tune but is highly recommended

 

agree I have a 07 5.4 I put the af1 cai 3" I ran like this until I got enough jing for tuner never had a issue didn't even set off any codes.I'm mechanically handicap and even I was able to install it, it took all of approx half hour and a beer or two piece of cake you'll be fine.
