A 99-01 intake manifold swap will give a small horsepower gain and a slight increase in fuel mileage.

K$N air filter, says to boost horse power to 10%, thats a big claim but I like mine. you can get a cheaper setup on ebay for arround 25$ and I routed mine to fit inside my stock airbox so it actually gets cold air

Just kidding.

O man I thought you were serious at first!!! those are a load of crap.

Run a bottle of 108 octane boost and fuel injector cleaner in your tank together. it feels like rocket fuel and get better gas mileage

put a performance chip in it. It wont necessarily increase power, but depending on which lane you choose it will change shift points and throttle response.

Whatever you do, don't get the crazy idea in your head of installing a throttle body spacer. The only that will flow better with that piece of junk is the cash from your wallet.

That will increase airflow into the intake manifold and increase both power and fuel economy... provided your right foot isn't to heavy. That's an upgrade I need to do sometime soon.
