Back when the injectors were in the throttle body, the spacers gave more time for fuel to atomize, increasing burn efficency. Doesn't do a dang thing with todays multiport injection motors.

Good article. Dirty maf's wreak havoc with codes on the Dmax forums. Kinda funny really.

Hi Guys.

new to the forum, but not new to trucks!

like someone else said earlier, those screens are to eliminate air turbulence and stratify the air while passing over the MAF. this reduces stress on the MAF wires, and also provides consistent air over the wires to reduce fluctuations in the sensor output. it does have a function unlike someone earlier had said. remove at your own risk.

cheers!

I cleaned my MAF just yesterday and it really is insane how different your engine responds after cleaning the MAF. Advanced had a special (buy MAF cleaner get throttle body clean for free) so while cleaning the MAF I also cleaned the throttle body as best as I could with it still attached. Cleaning around the seals of the butter fly valve has improved response time and even my shifting. I highly suggest people do this every so often to keep everything running smoothly and the way it should.

I have ran a MAF without the screen and with the screen and there was no difference.

Back on topic, I try to clean my MAF everytime I change air filters.
