OK, I'm planning on making a custom intake for my 3.3, but I'm having a few problems. First, 2.5 " tubing would be plenty, wouldn't it? Also, all the mass produced intakes have a rubber seal on the TB end. What could I use on the end of my intake to seal it air tight to the TB? BTW, I cleaned out my TB yesterday, it was real cruddy. I noticed a power gain, and the engine was a lot smoother up around 6k RPMs.
