Today, I cleaned up the TB. It was black as night before this. I drove the car (with the old paper filter) right after I cleaned the TB. It ran much smoother.
Always remember to check that stovepipe... All good.
AND... I finally got my Amsoil Ea filter today. Nice box.
It feels pretty sturdy. Really doesn't appear any different than a regular paper filter. The color matches my engine bay well.
I started the car. The intake was just a bit louder. Pulled out onto the road and WOW. It really makes a big difference. I drove around town for about 10 or 15 minutes and I can definitely feel it. The throttle is much more responsive and the engine sounds even meaner than before at 2500+ RPMs. I'm interested to see what this does to my MPGs.
FWIW, I want to make a few points:
-The new Amsoil filter made a huge difference in throttle response.
-My old air filter is only ~4000 miles old, so it'* still clean (this proves that the difference in power was not due to the switch from a dirty filter to a clean one). I'm actually going to keep it for a backup.
-Cleaning the TB only made the engine idle and accelerate smoother. It didn't really affect throttle response or power.
So, to sum it all up: Clean TB + Gutted Air Box + High-Flow AIr Filter =
