Dyno 2: K&N Typhoon Intake ProsTurbos need to take in air as quickly as possible. One of the limiting factors for the compressor is the intake. Nissan provides rubber intake plumbing with an airbox. K&N designed an intake pipe with an adapter for its trademark cone filter and the stock MAF sensor. Constructed of aluminum, the intake pipe is extremely lightweight and smoothes out the intake tract. The air filter has a large diameter base to help the turbo breathe as easily as possible. It definitely helped. Our peak power increased by 4.6 hp, but we realized as much as 7 hp between 6000 rpm and red line. Torque figures also increased by 2.1 lb-ft at the peak and by as much as 8 lb-ft between 6000 rpm and red line. You can really hear the turbo spool up with this intake system. ConsWe made decent power so we have nothing to complain about. NotesThe installation was a little tight, especially since the turbo sits low and close to the wall of the engine bay. Also, the intercooler took up a lot of space near the air filter. Different intercooler piping would have eased the installation.
