I have a split pipe on my Pug 106, it is a hot air feed to the ail filter. I didn't know there was one! There is a cold air intake, a "flap" in the pipe which the hot air line connects to, then to the carb via the air filter.
Picture attached.
Anyone shed any light on this?
Thanks!
it is to take warm air from the exhaust area to feed into the engine, in winter this can be slightly beneficial. If it is not there it will not be noticed. Most car shops used to stock it, some still will. If you really want to replace it, then do, but trust me, it is not important.
It also lets the engine run at its normal mixture setting a minute or so earlier in Winter than it would otherwise. It saves about half a cupful of fuel per journey, IME. The big cube on the right of the picture that both pipes run into should have a themostatically conrolled flap inside which attempts to keep the air going into the engine at more or less a constant temperature. They normally stop working after a few years.
It seems ages since we had a decent carb icing thread, doesn't it?

I blame the diseasels and other injected cars.
Diesel blockng the filters with wax, anyone?
please don't start that again. I was tempted to mention it, but was worried by what it might start, now you have gone and done it.
I taped it up. On ebay these 60mm tubes were going for silly money IMO.
