CAI does ZILCH, really think about it at best.

You want cold air to come into the engine, a cone filter mounted anywhere inside the engine bay draws air from where??? The hot engine bay! You get the kind or make one that is actually very close to the frontend it still draws in hot air somewhat. CAI is an oxymoron.

Unless you make or get a snorkel your not drawing in any cold air, only hot.

Headers, muffler/exhaust, MSD, and such will gain you something but not much. It isnt a muscle car, dont expect it to be one.

I noticed a great increase in throttle response after I cleaned the throttle body, it was all gummed up.
