What size torx bit to remove MAF

[davej_anderson]

The idle speed of my engine is sometimes a little unhealthy and having read a few posts on different forums, I thought that I'd try cleaning my MAF to see if that would help.

The torx bits required are the security ones with the hole in the middle so I bought a set.

I thought that the size was T20.

Now the set I've got says TS20 which I assumed would be OK but it appears to be ever so slightly too big.

Have I bought the wrong size or am I just really unlucky and have bought a dodgy cheapo set?

You may have the "security" style that has a hole in the middle of torx....hence the TS designation. You just want the plain T20 that you can pick up cheap at any Harbor Freight with the whole set.

At least on the early model cars (MY97-MY99), the torx bit that is required is actually a security torx bit. The size is T20 or, more correctly TS20.

If you look at the head of the two screws, you will see that there is a protrusion in the middle of the screws which makes the security bit necessary.

It could just be that the set you bought is just slightly off.

I've got the security style ones as indeed the head has the protusion.

Off to buy another set today and hopefully they will fit!
