I don't think my car likes cold air....

[IsaacCarlson]

I opened up the factory airbox and took out the restrictor "plates" and installed it in place if my spectre air filter and i think my mileage went down.....I even made rear wheel skirts and blocked half of the lower grille(all i can block without overheating). I also noticed that my MAF sensor was dusty, could you guys with paper filters just check and see if your MAFs are dusty? I saw that filter conparison and the paper filter missed almost as much dust as the K&N. Should i clean my maf sensor and HOW? carb cleaner????or do they make MAF cleaner?

The short answer, yes, they make it. Do I recommend it, only if you must. The MAF sensor is very delicate in most vehicles and susceptible and can be damaged easily.

No your MAF should not be dusty, mine never has been. OEM paper filters are best at filtering and flow plenty.

You need this

But electronic contact cleaner will do.
