go to www.need-4-speed.com/4.2corner.htm
and look at the mass air sensers..

which one do I want.
is the "race" that different then the bullet..
I want plastic but I need to know under normal driving conditions which should I get.

any help??
I just have the 4.2 auto..

 

One question.... Why do you need an aftermarket mass air?

You'd have to have a custom chip just for your motor to run the right A/F.

 

I have the chip.. so it will have to be reburned..

why mass air??? more power, and easy install.

figured if I'm going to open up my throttle body I should have as much air getting there as possiable.

 

Your looking at no more than 2-3hp max.

spend the money on a pulley or electic fan. You will have better gains with that. btw, the stock mass air is 100% effecient up to 360BHP. Complete waste on a non-heavily modified 4.2.

Only reason I'm going with aftermarket mass air is because I'm installing 42# injectors and I need a mass air calibrated for that and for supercharged.

 

oh, ok thanks.

live and learn.
