Was reading through the site (
http://www.rpw.com.au/shop/index.php...sk=view&id=202) of RPW (the ones who did all the mods on the mitsubishi 380) and it mentioned something about removing the lower part of the factory air box.
"Further options is to remove the lower section of the air box which is a separate part of the air box mounted onto the chassis and clips into the lower portion of the air box. RPW has found that this reservoir, which is factory sealed, if cut on the end enables air to be sucked into the air box. The air is sourced from the inner passenger side guard and not only provides further cold air, but additionally, provides around a 25% increase in air flow into the air box. RPW has successfully done this on many vehicles now with no side effects and fully protected from any water being ingested into the engine."
Also says
"But in all honesty, stock air box with the modified air intake on both ends is superior to an aftermarket cold air kit."
I already have a K&N air filter in my factory air box and was planning on getting the Fujita CAI but if it is better and cheaper to modify the existing box, I'd rather do that. has anyone done this?
