Firstly what is this block with the 2 water pipes actually for? heating the plenum or part of the cooling (doubtful with the air passing through it!)

Second the connection tubes look a little rusted up so are new blocks available or is it actually required?

Just thought I might as well put it right whilst I am playing around cleaning the and servicing my Plenum in the throws of completing a n/side rocker cover gasket change and polish/paint job. Just another day in life of wedge ownership.

The confusing thing about this then is that:
a) If it is using the heat to assist starting then there would be no heat there until the engine was running and warm anywayconfused
b) We all know that cooler dense air supposedly helps engines run better (maybe that's the 2bhp Glenn), so once running why design something that so called warms the inlet air, which is doubtful the velocity that air would be at through the Plenum anyway. confused
Everything would seem to point that it shouldn't be there no matter what the engine size.scratchchin

Well seeing as i don't intend using the car either in freezing weather or at an altitude any higher than the Lake District - i have removed it, now things are a little more clear, it really doesn't heat much up at all does it. You need to block 3 bolt holes up however, 2 that go through to the air inlet and one that goes through to the air pipe on the side.

Just realised that car should be faster now anyway as it will be lighterbiggrin
