Phenolic Spacers

[Mark Halligan]

Found these posted over on MotorGeek for anyone who is interested in cutting down on conducted heat to their IM. Available from here

Mark.

Is it an optical thing - or does the spacer not look like it has been cut correctly? Even hand cut?

And why is one bolt longer than the others?

Have you got one (or 2) yet Mark?

The longer bolt is to show you the length of the bolts supplied with the kit, cant say if it has been cut correctly but I would imagine it is?

I wont be using one, as the IM I am making at the moment is on the limit for space and the extra ~10mm will fook things up a bit I think, posted it for anyone who might be interested.....even so, why would I want two ??

To be different!

...........OK...........Don't know how effective these would be? But they might cut down on intake temps??

They used to fit something like this on the old Brit bikes to stop the carbs getting hot and causing vapour lock. Very effective.

They would certainly slow down heatsoak from sitting stationary - but I would have thought most of the temperature of the IM is from the air flowing through it when you are moving? Has anyone used these and measured any differences?

someone sells one here in the states for the 4-cyl 1.8t engines, and ive always waited to see one for the 5er. the tests for the 1.8t one didnt show any increased (or decreased) power levels at first, but after the 2nd, 3rd, etc.. dyno run....the power levels stayed consistent with little heat-soak dropoff, where as without the spacer heat soak took over and power dropped.
