From the Stillen site:
“Comprised of a high-quality polyurethane intake port, washable and reusable cotton filter element, and STILLEN's signature Aluminum Venturi Ring, the Intake draws air from outside the engine bay. The Venturi ring acts as a velocity stack, speeding up and directing the airflow into the intake chambers, making more useable and noticeable power. The Intake System also lends a more aggressive tone to the G35 and FX35 when pressed, but remains unobtrusive at idle. Every magazine that has reviewed these has raved about the G35's performance characteristics; and the STILLEN Hi-Flow Intake System is the perfect way to add an edge to yours.”
“Features & Benefits:
• Has connections for all factory breather tubes
• Comes with Poly urethane heat shield to isolate cold air directly into filter
• Utilizes genuine K&N filter with 1 million mile warranty
• Eliminates factory baffling, increasing flow efficiency
• Genuine K&N Air Filter w/ 1,000,000 Mile Warranty
• Limited Lifetime Warranty”
New: $269.84 + tax and shipping. Will sell my used for $150.
I am happy to sell the z tube and intake separately, but I recommend they be used together. I bought them as a kit and having both installed enhances the performance and sound more than just one or the other.
