Disabling Cylinders

[JoeWagon]

There is no 'easier' for the engine to suck in more air. The engine is going to create a vacuum and suck in air. If it sucks in less, with a stock filter, then you are going to get less fuel usage and also less power.

I put a short ram on my gs and i got better gas milege, but when i got an exhaust it felt ilost gas milege. so i dont noe...

well i get no better sleep at night if people don't agree with me, but at least they know my thoughts. If anyone wants to keep going with the thread, bring some proof or just leave it to be that driving has a lot to do with milage, and disabling cylinders is not a good way to do it!

I still believe a intake does improve gas mileage, but on my car a exhaust did not help it the gas mileage went down..

This says that they both do.. so who knows..

"Lots of other performance products can improve an engine's performance and fuel economy, too, including a high-flow intake system and a free-flowing exhaust. It's easy to understand why improvements to the intake system help: If you've ever tried drinking a really thick milkshake through a straw, you know how hard it can be to pull that fluid through an opening that's too restrictive. Your engine may be feeling the same way about incoming air.Exhaust system changes work pretty much the same way: If your engine is trying to force its spent gases out through an opening that's too small, it's wasting energy. Plus, if there's too much backpressure, some exhaust may remain inside your engine, which means there isn't as much room for fresh air and fuel to be burned, so you're making less power."
