The design of the Grimmspeed Cold Air Intake started as a solution to fill simple needs. They wanted it to not only be safe for the engine but also be able to run with or without a tune. They wanted it to be able to install quickly without removal of the front bumper. They wanted an intake that can make power all throughout the power range instead of just top end power. In the end, they ended up with a complete airbox system that can mimic the factory Air/Fuel ratio. Many Many hours of research and development went into this airbox before they were confident in the final product. They started with a 3d map of the engine bay to ensure perfect fitment of all parts. The intake tube used eliminates the 90 degree bend present in the factory piece. It is replaced with a hard inlet that offers a much more mild bend with better flow characteristics and not only decreases wind resistance, but also helps with accurate MAF (Mass Airflow Sensor) readings. The tube itself features an internal air straightener that sorts out the flow going into your engine. The tube then leads into the sealed airbox where the MAF sensor is located to keep away from the heat of the engine and headers to prevent skewed readings.

The airbox is laser cut, CNC bent, then riveted together before it is powdercoated with a heavy duty wrinkle black finish. The MAF flanges are CNC machined from 6061 aluminum while the intake tube is fabricated using custom bent tubing that is the perfect diameter for this specific application. Laser cut from the same 6061 aluminum, the air straightener is TIG welded into place. After welding, each tube is inspected and ported to ensure maximum performance. The tubes are available in either Red or Black for your choice.

The whole kit includes everything needed for install. It comes with the Airbox assembly, Intake tube, a high flow oiled air filter, 3ft of rubber sealing strip, noise generator delete plug, and all hardware to put it all together.

FEATURES

• You can have strong power in the high RPM and better response from open and close of throttle with air flow adapter casting short suction pipe and heat insulator.
• You don't need sound creator. The direct sound from the engine is good enough.
• We have stabilised the intake air temperature by shutting off the hot air from the radiator and set the cooler for fresh air with a shroud.

Features:

• Allows the restoration of a K&N Filter to new-like condition
• K&N conveniently sized 195ml spray for filter maintenance
• K&N Warranty applies to the K&N product range

Features 

• Designed to increase horsepower and acceleration while providing exceptional engine protection.
• K&N Air Filters are made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens
• K&N Air Filters allow dramatically more air into an engine
• K&N Air Filters are washable & reusable

Increase horsepower and style under your hood. PERRIN Performance intake systems use proper MAF alignment and plumbing size, both of which are crucial to maintain proper air fuel ratios and prevent check engine lights that plague competitors. PERRIN intakes are constructed from aluminum tubing, which is precision CNC mandrel bent, for consistent and perfectly fitting parts. The PERRIN MAF sensor bung is CNC machined for perfect fit and alignment of MAF sensor to intake. This is crucial for proper air fuel ratios and ECU engine management. The airflow straightener improves MAF readings by forcing incoming airflow into a uniform profile. Smooth and predictable airflow is the key to good, consistent MAF sensor readings for reliable horsepower gains.
