You probably won't see a great increase in throttle response, unless you're going to a ported TB. You will see a slight increase in torque, and a slightly deeper exhaust tone. Don't forget to make sure you plug the vacuum line at the rear of the intake back in when you do the install. If you don't, you'll be chasing an HVAC problem and won't know why. Also, while you're at it, change out the hard plastic vacuum line for a rubber one. It goes down to the canister under the battery. The line is inside the big wire loom. Just replace it and run the new rubber one down to the canister. Five minutes here and you'll save yourself a lot of headaches later when the hard plastic one breaks, and it will break. They all do eventually.
Glad you got the CLUNK fixed. Them noises can drive you nuts man!
