Ignition of cooler oxygen results in a greater charge of energy during the engine combustion process. The Z1 Motorsports M-Spec 350Z Cold Air Intake Kit takes advantage of this scientific rule by relocating the engine air filter away from the hot engine bay and retrieves fresh, cold air from in front of the radiator, thus providing more power to your 2003-2006 350Z!
The M-Spec 350Z Cold Air Intake Kit is constructed of a mandrel bent aluminum tubing, TIG welded, polished, and features an integrated MAF housing for greater airflow, weight reduction, streamlined aesthetics, and overall product performance.
Invigorate the sound of your VQ35DE engine with the M-Spec Cold Air Intake Kit with a deep growl in low RPMs and aggressive tone in higher RPMs.
Included in the assembly are custom-molded silicone couplers, ABA style hose clamps, and a reusable K&N air filter for durability. Unlike other cold air intakes, the M-Spec Cold Air Intake Kit mounts the K&N air filter at the highest point possible to avoid water consumption and hydro-locking the engine in wet conditions.
This kit is will not bolt on to G35 coupes & sedans without modification of the radiator core support to allow room for clearance of coupler and piping.
This Race Version is only intended for use with vehicles that have the ability to tune their Air / Fuel Maps. The diameter of the race version is larger than the diameter of the stock MAF housing creating a lean condition if the map is not corrected. DO NOT USE THIS INTAKE WITHOUT GETTING YOUR ECU TUNED!
Z1 offers E-Tune services for those with existing Uprev Licenses or choose to purchse the Mail-in Flash and receive your ECU flashed with the M-Spec Intake in mind.
