Gruppe S header install question
 

Hi guys,, I just bought a used Gruppe s ceramic coated header and will be installing with new OEM gaskets in a week or so. Question is do I need the reflective heat shield that goes on the oil pan ? Car is street driven only and not abused. I don't think I will get the oil too hot but will the header blister the paint on the oil pan ? If so I will get one. Any advice appreciated.

Plenty of people installed the header both without ceramic coating and before the heat shield was available. You should be just fine for street driving the car.

Although I think the Gruppe-S header is shaped slightly different than the Tomei UEL, it still comes pretty close to the oil pan and the thermostat housing. I'd say if you have it and are under there...put it on. I don't think minimizing heat transfer would be a bad thing.

Since it's ceramic coated, I'd say nah

Thanks guys. I may just put a piece of insulation wrap on it where it passes near the pan with a SS band.

I have a Gruppe-S with the heat shield (uncoated), and oil temps stay around 210 degrees F just driving normally. When I do spirited driving on backroads for a little bit though, it’s not hard for it to reach 240 degrees F

If you don’t drive hard too often I’d say you’d be fine without it, but the less heat the better.

You don't have to use their insulated piece. You can buy a stick-on roll of the stuff for like $15 and have plenty left over. Its worth the piece of mind

I have the heat shield on but I had mine ceramic coated too. My average temp is closer to 203 degrees F and when driving it really hard I get to 220 degrees F.

Thanks ! Where did you buy the roll ?

A little more expensive then I remembered but plenty to work with. Has a weave layer and a reflective layer
