I've searched and searched but all I'm reading is drill the hole out. Which hole do I drill out and how big do I drill it out to.. ?

Thanks

Left hole 1/2 inch right 1/4 inch.
left as in looking at it from the front of the car? or from the drivers seat? :LOL:
This has 3 holes in it. Looking from the front of the car head on. 2 Holes on the left side, and 1 on the right.. Ones on left side are 3/8" and larger one is 7/8".. Angled ****** on right is a little larger than 3/8"...

Are they already the correct sizes?

K+N is doing a test dyno car (again) this week, generously loaned by one of our customers. They plan specific varied hole size dynos, but they swear by the 3/8 PCV line opening (Left Side Of Car, right-angle straight out) and doubt that bigger is better. But THIS time its a 1-goal test. Making sure of the optimim hole size.

They do admit that some early units did get out w/ smaller holes, and they have EXCHANGED those for our customers who discovered this and preferred exchange to self-service.

Please stay "tuned"
