The Injen Speed Pro series intake systems for the 2007 - 2009 Nissan 350Z and Infiniti G35 are a game - changer. With special tuning tech, they offer top - notch performance gains and maintain a safe A/F ratio. The patented Mega Ram system cleverly constricts the air intake at one point and then boosts airflow elsewhere, supplying the intake manifold with the maximum air. These Injen SP intakes are precisely tuned for your vehicle, engine, and ECU. Unlike other air intake systems that might make the engine run too lean and cause overheating or damage, the Injen SP ensures cold air flow for both great performance and engine safety. By reducing turbulence and providing a smooth flow through the high - performance filter, these intake systems increase horsepower and torque compared to the stock setup. Injen has recorded gains of over 10 HP and 10 ft/lbs of torque! Each intake is made of 6061, T - 6 aluminum alloy and comes with an Injen performance dry air filter having a built - in velocity stack. A replacement windshield reservoir bottle is included for a perfect fit. It also comes with stainless steel clamps, high - quality silicone hoses, and instructions.

Using this Injen cold air intake is straightforward. First, follow the included instructions carefully to install it. Make sure all the stainless - steel clamps are tightened properly and the silicone hoses are well - connected. For the best fit, don't forget to use the replacement windshield reservoir bottle. When it comes to maintenance, regularly check the Injen performance dry air filter. If it looks dirty, it's time to clean or replace it. This will keep the airflow smooth and maintain the performance gains. Also, keep an eye on the engine's condition. If you notice any unusual noises or performance drops, it might be a sign that something needs attention. Remember, this intake is tuned for your specific vehicle, engine, and ECU, so don't try to modify it without proper knowledge to avoid engine damage.
