do they make one for the 1.5L sohc? if so, where? if not, jrm how much would it cost to get one made up?
Molded from phenolic material for superior heat insulation properties between the lower intake manifold and upper plenum for more power.What is a phenolic spacer and what does it do? Advantages and disanvantages.
Fair enough. But heat only has three ways to get to the IM that I can think of:i know that some of you guys have got them and reckon that they work, but i still dont know how something that is about 3mm thick can make that much of a difference !!
oh trust me it matters! I've done tons of phenolic spacers in the past and love them (epecially for street use on a hot summer day, you see VERY noticeable differences in intake air temp!)Dyno proven results would be great with something like this. It would seem that by the time air travels that far, it would be at such a velocity so that manifold temperature would not matter enough to make a difference. Additionally, since you would be isolating the intake manifold from the motor itself, you are in effect decreasing overall surface area for heat to disperse and you would run hotter and potentially increase the chance for early detonation. So it would seem anyway.
