I been hearing all around about cutting out the bottom of the box where my K&N filters go but im not really sure what is it that you suppose to cut some help would really be appreciated thank you... (1986 Camaro TPI 350)

 

It's really easy. Remove the "Y" intake tube. Remove the K & N filters. Look down into the "boxes that house the 2 filters. There are 4 total air diverters (2 in each box). remove them. This alone will help the intake breath better, but not much. Once removed, use a Dremel drill and cut out the bottom of the boxes. You can also cut out the bottoms by using a "Saws All." But you will need to do a starter cut to insert the saw blade into the area that is to be cut. Make sure you use a Fine tooth blade. I say agian, Make sure you use a fine tooth blade. If you use a blade that has jagged large teeth, you will damage, crack, or even worst, break the whole filter base. So be carefull.

 

Thank do you know if it really helps did you feel a difference when you did it on yours whats the increase on doing this sort of work?

 

It made a difference when I did it. Its not 10hp but its real.

 

How did you do yours???

 

I went with the fine tooth saws all blade. The difference in performance is that I get a bit more of a jump from a dead stop. This is so because there is far less air intake restriction. The gains can be from 1 hp to 5 hp. It'll vary from car to car by means of altitude, summer vs. winter (cold air is denser and will give more hp) and engine mods.

 

Do you think a stock 87 350TPI with ceramic headers and 3" exhaust would benefit from this?

 

I just did mine using an air die grinder and a cut off wheel. It's a mop...it cant hurt. If your worried, do what I did. I went on the forums and asked who had a spear and bought it just in case. Easy to do. 15 mins

 

Thanks Guy I just finished mine and it came out perfect just came back from a spin and you could deffinately feel a diference in the cars push when in take off..yea i think it would benefit even still with the headers cause all those baffles are doing in reality is lowering your air flow....once again thanks guys!!!!

 

 

wanted to say i removed those air dividers and wanna cut out the bottom like you guys have done but i dont have a dremel or any cutting tool, so how much does a dremel cost that will work ok for basic stuff? thanks.

 

If your just looking to buy one for basic stuff, I won't purchase a Dremel (brand name) as they can get pricey. I have a mastercraft 'dremel' kit and it works great. Cost me under $40 and has a bunch of attachments. Its one of those tools you randomly need and its good to have!

 

You can also use a drill to put in a hole and then use a hacksaw blade to cut around. More time but also no cost if you have those tools. Prob easier to borrow them as they are more common.

 

Yup. Drill a hole and use a fine tooth blade along with a Saws All. If you have a friend who does carpentry, he'll have one or knows someone who does.
