If I run sea foam through the brake booster line, will it clean the egr line right past the throttle body?

 

i dont think it will. the EGR blows in to the intake manifold, so even if you fed the seafoam spray into the throttle body (AFTER the MAF) it wouldnt clean teh EGR.

i guess some of the seafoam would get recirculated though the EGR though, so wherever you fed it it would go throught the EGR, im not sure how effective it is though.

 

I'm not sure if it hits the EGR valve, but if you want to make sure just disconnect the hose running to the EGR and suck it in through there. The sh*t works great.
