on my 86 305 4bbl firebird i wanna change my air assembly to a K&N http://www.knfilters.com/search/prod...x?Prod=60-1640

i was looking at the factory assembly and theirs alot of tubes connecting to it...theres a tube on the left side i think goes into the valve cover...on the other side its conected to the headers

so my question is what do i have to do to put in the K&N

thanks for bearing with me

 

The one tube that goes into the valve cover generally goes into the manifold, not the Air Cleaner. This is your PCV valve hose. Not sure what the tubes going to the headers are for.

Is it a snorkel setup you have on top of the intake now? I know on the TBI cars theres a few lines going to that, is this what you mean?

 

ya its the snorkel setup..i'll take a couple pics to show u what im dealin with

 

i hope these pics help with my question...let me know if u need more

 

The factory air cleaner has the snorkel, heat stove pipe for the thermac valve, vacuum line for the thermac valve, and the PCV filter breather hose.

 

are all those things absolutley needed cuz i really wanna put a k&N on it but it dosent seem possible right now with all this

 

The K&N air cleaner you're looking at doesn't have a snorkel or thermac valve, so you don't need anything associated with either of those. I believe it has a fitting for the PCV breather hose.

 

and just so im clear thats the hose in the 3rd pic right?

 

Right
