I have a 1999 Toyota Camry, I want to put some stuff in it to make it have better gas mileage and maybe go a little faster. The one thing I want to happen is a faster response time on the gas. What kind of things can I put in it?!?!?!

K&N drop in filter so your engine can breath better, free flowing exhaust like a Greddy or HKS so you can accelerate faster plus it saves more gas as long as your not getting on it but remember you still need back pressure cause your still running all motor, hot NGK irodium spark plugs with bigger plug wires, upgrade your ignition coil or enitire ignition system to ignite all that gas efficiently through out your RPM, and run full sythetic oil. Freeing up the congestion that your car would have from factory saves you gas plus it makes HP too. Don't forget you use more gas to if your hot rod'n your car out. But at least you'll a some more power to use out of all this. I'll just stop here because i could go on and on about tuning cars. I hope it sheds some light what to buy for your car.

I had a 1992 Toyota Camry. I would buy one of those portable fans you can plug into your fuse box. Instead of using the Air Conditioner... use a fan to cool off if you can.
