Do worry about rubbishing my design, only something I knocked up to test
Intersting test though, you are right my heatshield is made out of polished stainless steel, that's all I could find to work with.
Did not think about enclosing the MAF also,something for MKII perhaps
. Also like Warmonger, I think the factory air inlet is not enough, hence the next thing to try is to get more in. What interested me was atfer driving, the airfilter is a lot cooler to touch and the heatshield is only barely warm. What appears to be happening is that at idle / low speed, the heatshield is reducing the air temp by a small amount but as the speed increases, the air rushing in the front of the car is sufficient to not be heated up greatly. With the heatshiled in place, this air cannot get at the fitler so effectively. Anyway, an intesting start, I will mod the air intake and repeat the tests, I do like your design Jeff
