Custom Second Gen Air Intake
One of the many stupid things toyota did on their second gen 4runner’s with the 3.0, is their whole intake system. Many silencers and air boxes all unnessiary and decreases horse power and acceleration.
I looked up online and found many cheap intake systems on ebay with the common cone filter on the end…bassicaly all for show and noise…a bad idea when you do a lot of offroading especially if you live where it gets wet a lot. Not finding what we wanted on line we set out to build our own system that worked with the already exsisting mass air flow sensor and air filter. So we made our way down to the local home depot and bout the following
The we went to a local exhaust place and were able a steel 3″ pipe with a 40% bend a perfect fit with a few cuts.
Mock up the design with Dryer flex pipe.
Using the dryer and the hose couplers install install the pipe and make your bends carefully to get the shape and size your need.
Use Flex Pipe to Make Cut Marks on Steel Pipe
Taking your flex pipe make your marks on your steel pipe so you can cut it accordingly.
Cut Steel Pipe to Fit
Drill two Holes for Remaining Hoses That Need to Be Attached
Make Final Clean Cuts and Clean the Hell Out of It
I wanted to make sure it was really clean so after everything fit it cut it which a metal cutter and ran a wire brush though it till there was no dirt or bers.
