Filthy MAF

Got round to cleaning my MAF at the weekend.

Urgh, the boy was dirty! The screen on the airbox side was completely black and, slightly worryingly, the screen on the turbo side had melted?

Anyway, left in IPA for a few hours and it's all shining and spotless now. I've left the airbox side screen on, but removed the debris of the screen on the turbo side, I can't see what it's for anyway.

On first impression, the car seems to have now not got the intermittent low-end hesitation, but I'll need to do some more miles to really give a verdict.

Easy to do and worthwhile bit of maintenance. It shows you that the air filter has a hard job and stuff still gets through ...

How did the MAF screen melt?? Do you have the standard airbox or a cone filter? Jeez, I'd be worried if if found that. I presume nothing made it's way into the engine

It's a standard 3B airbox and standard air filter yes. The turbo-side screen was a gnarly mess, but perhaps "melted" was the wrong word. It was certainly damaged.

I also really hope nothing ever made it in to the engine! Maybe that's why I get flames sometimes, it's bits of the screen
