had my car serviced & they changed leads + plugs the leads didn"t have the heat sheilds, and have some melting on manifolds . ive been trying to buy the leads with heat sheilds with no luck. anyone know if i really need heat sheilds. thank you
leads with heat shields are only available through holden fro some reason. my car didn't have them for the first 2 years i had it, didn't seem to make a difference. only reason i added them on mine was because factory leads were the cheapest i could find
also depends on the quality of the rubber / silicone leads and boots. Cheap ones will suffer more from heat than good silicone ones. Try to keep the leads off the exhaust with some clips or something. And if you find a set of heatshields, keep them and re use them each time you change your leads
thanks everyone got a set with heat sheilds from REPCO about the same price as others seems to have a little more pick - up an runs alot smoother . thanks
was going to say, wreckers have millions of them, but you shouldnt need them to stop the leads melting, they are to help prevent heat soak, leads should only melt if they are fouling on the manifold, otherwise they are crap leads.
