Well, I just got my unlimited products 2 1/2" cowl hood in yesterday and now its time to buy an open element. I want to buy the 14" by 5" one that raises 9/16" above the flange. I have a 5-18" base right? also what do I do with the breather and PCV? Sorry I didnt mention its an LO3. The other stuff I figured I would drill holes in the base to mount it. Thank you!!!

 

I used the knock outs in the filter base to mount the sensor and breather. What does the new hood look like? I used a flat base to get rid of the spacer.

I forgot. the base you mentioned is the right size.

 

The 14x5" will fit under the new hood (2 1/2" cowl) don't you think? Has anybody put the 14x5" on their car, or have pictures of it? I want to get the X-treme k&n lid for it, too.

I'd rather be historically accurate than politically correct!

 

I don't know if the 5" will fit. my 3" was tight with the tbi spacer in. I tried a triangle filter that was open on top and the filter mesh was pressed into the hood pad.
