Hi all,

I'm usually over in th 335 forum but I also have a 1997 Shasta 21' RV on a E350 chassis with a 460.

I could use a little more power of course. I can't find a cold air intake system. I tried removing the intake silencer but it's just too much noise. I do have a K/N filter.

I want to stay with reg. fuel and not make a lot of noise. It's already kind of noisy going down the road. Almost all of my driving is above 5,000' ASL.

Thanks for any thoughts.

Harold
