6637?

[Jweber0660]

I know the 6637 works great on the 7.3 but had any one tried to make it work on the 6.0? Please share!

From what I hear the stock 6.0 air filter does really really well in terms of flow and filtering ability.

^^ agree...the 6.0 filter is an awesome air filter...much better than the stock(98% efficient at course dust) 7.3 and filters better than the 6637(99.9% efficient as course dust).

Don't get me wrong the 6637 is a great filter, but if I had the cash I would have gotten a AIS intake, same filter media as the 6.0 intake.

If you plan on 450-500rwhp then you will have restrictions but for a stock or near-stock truck it is a good filter.

Leave the stocker in there, until you go with a turbo and sticks . It's good for about 500hp

I'm going to move this to the 6.0 performance section

Wasn't there a thread on the nation about this? A guy installed one, which looked rediculous and over-crowded the engine bay. I believe the 6.0 filter outflows the 6637 by over 100cfm, don't quote me on that though.

And as far as injectors and turbo, I have 175/100's and a pmax. I had an S&B intake on for a while, I had a wth kind of thought and put the stocker back on, not one bit of difference on anything(power, egt's, etc....).The S&B is sold now. Just leave the stocker and go on with other things.
