Gruppe S + Helix up-pipe question
Im sure this has been asked before but ive just bought some gruppe s headers and helix up pipe and there are 2 threaded holes (one in the headers and one in the up pipe) can anyone tell me what thread sizes they are and what i can use to plug the holes
thanks in advance Daz |
Boss on headers is for Lambda probe - M18x1.5 - Engine core plug fits nicely.
Boss on uppipe is for EGT probe - M12x1.25 - Cut down a M12 fine bolt. Andrew... |
thanks Andrew.
me and daz have both got to fit a set each in the next couple of weeks :):) |
Cheers Andrew,any ideas where i can get these 2 bolts from,is there a stockist that will have those size bolts in stock?
|
Darren I used a Toyota sump bung in the Helix up pipe, TSL can supply a lambda probe bung but you might be able to get 1 from a local exhaust stockist cheaper, someone like Southern Exhausts.
