How's it going, I have been reading up on gutting airboxes and was wondering if there are actually any performance gains? Such as performance I can actually feel? I have been considering this because it is free and I'm a high school kid, so money is pretty tight. Any help would be greatly appreciated, thanks!

 

I've noticed that my tires chirp more often during the 1st to 2nd gear shift during the winter when I drop the gas pedal.

 

Worked for me- especially at higher speeds.

 

There is a thread here somewhere where a person went even further. He used a heat gun or a hair drier to soften the plastic and re-form it to make the passages larger. Claimed that it also helped.

A search may bring it up, I wish I recalled more about it for search terms.

I dis see thread where a guy seperated the upper and lower section of the dual intake. He then added around .5" inbetween the upper and lower section of the dual snorkel housing. I don't recall the results. It's been around a year since I read the mod.

 

I gutted my air box and it helped a good bit. I later made a ram air intake that made a real difference. Both modifications are definitly worth it.

 

It's a free mod might as well. with airflow going stright though instead of going though baffles and mazes.

I noticed a difference.

 

I did it years ago. I really haven't noticed any difference.

 

I noticed a slight increase in pull but nothing to ride home about.. Hard to say if it's psychological or real world improvement.

 

Gutting the air boxes certainly won't hurt anything, but as far as performance goes, you probably won't notice a difference. With all the research I've done it seems that the base intake manifold is the biggest restriction in the fuel/air delivery. Until you upgrade that other mods (throttle body, runners, ect.) won't have a big effect on power.
