Popular Post kpr Posted October 27, 2021 Author Popular Post Share Posted October 27, 2021 Modified the plenum cover. Bit more volume and big inlet, probably about 6" into box, into 4" pipe. by itself, it pulled less vac at wide open throttle vs the stock cover Then hooked the stock air filter box up to it . The air filter lid even tho stepping down to 3" and the filter element itself were hardly a restriction at all. but the feed pipe into the bottom was a straw and it acted pretty much identical to what the unmodified plenum cover did with no feed pipe attached. so mr toyota made the parts suck equally. or suck less equally? so cut a big hole in bottom of air filter box which fixed it. then added a feed pipe which sits over a factory hole into inner guard. for some cold air 113kw. Still running the little factory exhaust! just the front pipe mod. 24 1 Quote Link to comment Share on other sites More sharing options...
