I have been asked what is so special about PTFE, and why is it so expensive, so this may shed some light on the stuff.
"PTFE Sheet is officially in the record book as having the lowest co-efficient of friction of any soild material and is extremely effective operating at very high and very low temperatures. It has fantastic chemical resistance and superb electrical insulation properties. PTFE Sheet can be tricky to bond, but it is non melting and is self extinguishing"
So they're relatively soft, which is good because they compress a little bit with 20 torque and seal well, they'll even move enough to seal light scratches in the alloy, just make sure the mating surfaces are really clean and there's no oil/grease or bits of the old gasket left to be seen on there. They will also reseal a fair number of times, probably ten, but if you use a standard gasket either side of the PTFE they will last the life of the car.
this is a from quote from Phillip ( hope he does not mind) :
"Massively reduces the heat transfered to the manifold, and therefore to the inlet charge, resulting in cooler, denser air entering the cylinder, giving better cylinder filling.The effect is much the same as fitting a cold air intake kit, but as an added bonus:
1) You no longer get heatsoak after sitting in traffic, so no sluggish engine response as the traffic first clears
2) The slight increase in induction length also helps bolster the low end torque slightly, increasing the effect of the gasket in the low and midrange"
end quote.
hope that helps to throw a bit of light on it.
I bought some 3mm PTFE from someone on another forum, it is pretty easy to handcut the throttle body shape, but I would put original gaskets either side, so that they do not deteriorate no matter how many times you take the body off.
super stuff Alee, you can pay me 23.50 via paypal to pcourtney1@gmail.com, or if you would prefer you can pm me any other payment method you would prefer.
all the best
