Replacing air cleaner with aftermarket.

[Brian Blanton]

I am replacing my factory air cleaner with an aftermarket air cleaner.  What do I do with the exhaust gas recirculate opening in the exhaust header?

You are just talking about that tube that pops over the exhaust manifold right?

 

If so, you can do nothing with it and that is fine. Pretty sure they just do that to help bring in warmer air into the intake. The exhaust manifolds get warm really fast and warmer intake air can help it run smoother sooner.
