just got invidia exhaust mani & 02 housing and i was wondering if its going to throw the check engine light?

if so can you use a spark plug anti fouler?

 

It won't, or it shouldn't.

 

ok thanks!

 

why do you think they will throw CEL? they are not emission device like a cat.

 

Don't forget to replace the mani studs or they will start to pop off randomly down the road. I would replace them with stainless, do the job right the first time, and it will save you money and time down the road...

 

where can i get ss mani studs from? they dont come with the manifold?

 

This is not true. I've replaced so many exhaust manifolds and o2 housings I can't even count them anymore and never once have I had a problem. Just reinstall the new stuff using the stock bolts/nuts/studs and you'll be set. If you have a lower mileage car you can even reuse the stock stainless steel gaskets without worry.

 

If your studs and other bolts are backing out you need to check your timing.

 

i have 35k miles on my car but the bolts are all rusted!

 

really i was about to buy arp manifold studs, you dont think i need them?
