The Injen Speed Pro series intake systems are designed for the 2003 - 2006 Nissan 350Z and Infiniti G35. They use special tuning technology to boost performance and keep a safe air - fuel ratio. The innovative Mega Ram system restricts the air intake at one spot and then maximizes airflow elsewhere, delivering the most air to the intake manifold. These Injen SP intakes are precisely tuned for your vehicle, engine, and ECU. Other air intake systems might make the engine run too lean, risking overheating and engine damage. But the Injen SP ensures optimal performance and engine safety with its well - tuned cold air flow. By reducing turbulence and providing a smooth flow through the high - performance filter, it can increase horsepower and torque compared to the stock setup. Injen has achieved over 10 HP and 10 ft - lbs of torque gains! Each intake is made of 6061, T - 6 aluminum alloy and comes with an Injen performance dry air filter with a built - in velocity stack. It also includes stainless steel clamps, high - quality silicone hoses, and instructions.

Using this Injen cold air intake is easy. First, refer to the included instructions. They'll guide you through the installation process step - by - step. Make sure to double - check that all the stainless steel clamps are tight and the silicone hoses are properly connected. When it comes to maintenance, regularly inspect the performance dry air filter. If it looks dirty, it's time to clean or replace it. This will keep the intake system working at its best. As for usage, drive normally. The intake is designed to improve your engine's performance in regular driving conditions. Just be aware that in extremely dusty or dirty environments, you may need to check the filter more often. Avoid over - tightening the clamps as it could damage the hoses or the intake components. Also, don't use any harsh chemicals on the filter or the intake parts as it may affect their performance and durability.
