Frequently asked questions

Can I weld it to steel pipe?
No, it's aluminium. Weld it to aluminium pipe.

Where should I mount the MAF?
On a straight section with a few pipe diameters of straight run before it for a clean reading.

Weld it in, plug in the factory MAF and you're away. Bloody handy for custom intakes.
