A 4" pipe would be a slick idea but you you would either have to find a filter with a 4" inlet or work out some kind of a reducer to get the K&N 4750 to work.

A built Series 2 L67 can't outlfow a 3" pipe.

it looks so skinny




thats my 3" intake, is yours 2.5?

Optimus....Looks like you merely zoomed in closer.

How is that sewer pipe coupler working out? Any issues when it gets warm?

Interesting comparison between those two pics posted above. Notice the much more gradual turn on the rice pipe? Much preferred over a nearly 90° bend. That bend restricts flow in a big way.

No, it'* 3". Can't you tell? It'* Huuuuugge!!
Is your throttle body one of those miniature models??

Tumbleweed

(couldn't resist temtation)

LMAO!!

Man, that'* nothing. Check out my oversized injectors!




And remember, the higher quality the jpg, the better the flow.

ok seeing is that you think your right 100% of the time...we are not talking about the rate of flow...we are talking about how laminar the flow is...untill you understand fluid dynamics.... the set up with the gradiual bend is FAR superior to your 90*....and your filter is still a sponge

Optimus, your attitude prevents you from having an open mind.

Your 90 degree bend is the worst thing you could do with a piped intake. Period. Fluid dynamics obviously escapes you, as have all the succesful intakes we've built here.

On top of all that, I can't get over your unusual insulation placement. We're trying to reflect heat BACK to the filter, right?
