I was wondering if I'll need reducers for a K&N 57 gen.II intake.

Also, I'm about to install a throttle body spacer. I was looking at this item called "The Turbonator", it seems to do the same thing that the spacer does
-swirl the air so it mixes with the gas better- I'm wondering if it will still increase my hp when combined with the spacer.

If anyone knows about this or has tried it already, please gimme a shout.

 

in my opinion spacers, and those little air intake turbines that just spin the air. Are gimicks.

 

i have a k&n air intake system and i think it was a good buy for about $280, but i did have a throttle body spacer on and had to remove it cause of the angle it was putting on the intake tube.
