Spectre's universal mass air flow sensor adapter is designed to allow you to add a 3 inch flange to your mass air sensor housing. This setup allows you to attach a 3 inch clamp-on air filter or a 3 inch diameter tube directly to the stock mass air sensor. This adapter is constructed with a combination of aluminum and co-polymer ABS components for a great look that is durable. The adapter's flange has a 3-3/8 inch by 2-3/7 inch bolt hole setup for multiple bolt hole configurations.
