OK I am new here, but I haven't found to much on here about intake systems. I need some opinions on which is best. Let me know what you have and how you like it. I want one, but I want to make a wise choice. Thanks!

 

for what kinda truck? i think AF1 is pretty good and so is S&B

 

We really need to know what engine and what year. Also, please read this thread, it touches on your question.

I have an 04 with 5.4l.

 

Might I add that I also have the edge programmer. I am thinking of getting exhaust also. With the intakes, I ave looked at the S&B and the K&N.

 

Ok, I would not dare get a CAI until I had custom tunes. The 04 and 05 5.4s came from the factory in a near lean condition. ANY additional air can cause them to run lean and damage the engine. The Edge tunes are specificaly for a stock intake. You can convert your Edge to a Gryphon and get custom tunes that solve that problem. A CAI adds little unless you have a custom tune, anyway.

 

Ok. So i should go with the exhaust first? I have read on here about exhaust without the cats. That doesn't make the engine light come on? What would be the best exhaust set up for me to tell the shop. In know the guy who owns it, so he will do whatever I say.

 

Exhaust from cats back will not cause a problem at all. If you start removing cats, it can, or if you put headers on, you need custom tunes for sure. You have a sensor in the cats that has to be dealt with as well, if you mess with them.

 

Ok, so I do cat back exhaust. What brand do you think is better. i have always had flowmaster but there is a lot to pick from.

 

I do exhaust for sound. I love the sound of the Flowmaster Original 40, but if performance is a big thing, I think you lose a little low end torque. No big deal to me. The Magnaflows are better for performance, from what I have read, but they are just too quiet for me. If cost is not a big issue, the Borla or the Roush Offroad have great sound. The Roush sounds much like the Flow 40.

 

AF1 went out of business. Just fyi.

 

Doesn't disprove the fact that it is an awesome CAI. One thing that makes them so good is that there filter are S&B filters.

 

exactly i still dont have custom tunes BUT do have an S&B CAI which i am dyeing to put back ion i got the S&B drop in and did the gotts mod to hopefully help

 

Last I knew, Troyer was still selling their kits...

And another vote for AF1.

 

I like my $80 ebay special that came with a K&N filter!
