BLOX Racing 2003-2005 Nissan 350Z / Infiniti G35 - 5/16 Thermal Shield

If you're installing a cold air intake on your 2003-2005 Nissan 350Z or Infiniti G35, you'll want to protect it from engine heat. This 5/16 inch thick thermal shield from BLOX Racing is designed to do just that, helping to keep the air entering your engine as cool as possible.

Keeping intake air temperatures down is key for performance, especially with aftermarket intakes. Cooler air is denser, meaning more oxygen molecules can fit into the combustion chamber, which can lead to a more efficient burn and improved throttle response. This shield is made with materials that reflect heat away from your intake piping and air filter, ensuring that the air charge remains cooler.
