Hi guys, its my first thread here.

So, i put on my a CAI for my 07 rx8, everything was working fine, but you know the CAI doesnt have place to put the vacuum, not like the old air box, so where should i place that? or just take it off?

thanks for reading!

 

Cap it

 

Just go through the instructions and you'll be fine.
Page 5 of the installing manual instructs you to remove the VFAD vacuum lines.

 

The intake should have come with a small black vacuum cap to cap off the VFAD when you remove the lines. Just make sure the cap is firmly on.

 

"Black Cap"? i dont think it came with it, maybe its missing. what does the cap look like? just wondering.

 

you cap it with a nipple, you can get one of those at any autozone/pepboys


here's what it looks like, go to this thread and look at the picture

cool thanks man. ill go get one tomorrow.

 

Say if this wasn't caped , what Type of code could this throw out? When Mazda replaced my engine it was torn off now I cannot access it to cap it off due too it is now more of a hole then a hose line I could weld it close is the only thin I can think of to secure it co
Pletely or is there a way i can replace the whole thing ?

 

I'm not sure which vacuum nipple you are talking about. Maybe it's a language barrier, try and post a pic.

 

Its the vfad hose just coming from behind the throttle body , this was capped during the aem cai install but now was cut right to the base now leaving an open hole

 

Ah, ok. Well that is plastic. You could try using epoxy to fill it but there is always the danger of it coming loose and getting sucked into the engine. The best best is to replace the upper intake manifold.

 

Wheres the Best place to pick one up online? I check out rx7store but I could not find any for sale

 

Try the parts for sale section in the forums. I know I've seen a few in the past few weeks

 

I have an extra one but I'm not sure about shipping it to Canada. But if you can't find anything make me an offer and we'll see what we can do.
