Took the car for an MOT yesterday, but the car boiled when I got there 110° !!

Car drove perfectly on the way there,otherwise.

I switched off during the test and refilled the system, got off the ramp and the car was driving like a bag of the proverbial ! - first thing that came to mind was the MAF again, sure enough after nursing it home I replaced the unit with a cheap Chinese eBay item £35.00 and it corrected all the faults and drove beautifully again.

Obviously the engine bay heat is killing them, this is the fourth one in as many years I've fitted, by now getting a little fed up swapping them out on a yearly basis!

Has anyone prescribed the same issue with the suicidal positioning being taken into account, and moved the MAF further forwards, away from the L.H. exhaust manifold 'killer heat' area?

I've wrapped it in one layer of aluminium heat reflector / insulation foam for now, but wonder what's the next best position I should move it to, just behind the radiator ( but still close to the elephants trunk manifolds) or Infront of the rad in the nose area?

Anyone done this (or have you all done it already?) - any issues to be aware of regards extending the wiring, or possible water ingestation from the grille area?

Cheers,
Phil.

Some fit a heat shield and leave it at that, there used to be a wrap around jacket available for it too.
I was under the impression the Maf is supposed to be close to the throttle body but not sure if there is any truth in that.

I've had 3 x Chimaera and now a Griff, I've never had a failed MAF. One Chimaera had over 80k miles on it, and I've never added extra protection either. Used on very hot days too. Have I just been lucky?
