Air Box Mod on a Hardbody D21/ Pathfinder WD21 and R50 Pathfinder (Cold Air Intake style) |
This mod is similar in
technology as a Cold Air Intake system. You should get 1mpg better and more
power, with an increase in noise. Tools needed 10mm socket and phillips
screwdriver. 1" drill bit and electric drill. The w/d21 mod is basically
modifying the air box that houses the air filter via
some extra holes. The resonator in the fender can be discarded later.
The R50 mod is basically modifying the resonator (muffler) box that is hidden in the fender not under the hood. The air box that houses the air filter is connected to the resonator box via a huge hole. Benefits to this mod:
W/D21 version
Engine was breathing through a tiny tube. That big tube dead ends in the resonator in the fender.
R50 version
