NISMO R-Tune Cold Air Intake System:
NISMO CAI features Black Powder Coated 6061 Aluminum Mandrel Bent Tubing, NISMO Logo, Water Bypass Valve and Washable Intake Filter. (K&N style cone filter)
It has been used for about 1 1/2 years, and I just sold my 2005 Altima SE-R, so still have the intake. The sound is unbelievable, and ones you feel the mid/high range pull you will love this mod. Plus better fuel econopmy, but you won’t be able to keep your right foot away from hearing more of the intake.
Nissan Performance Mag did a review on the intake: They had 216.9 baseline, 229.0 with Nismo CAI
Looking for $200
