Removing maf sensor

Use some pliers to hold the top side of the bolts while you unbolt the nuts on the other. Trust me! too many others ended up breaking those plastic "encasements" in the air box cuz they're just not strong enough.

Yes! I'm not sure why you mention a Ralliart since you've got a OZ Rally...right? There were 4 bolts on my MAF that I had to broke loose to bolt up the shield for my RMR sri intake.
