Does anyone have an S4 airbox for sale or can recommend a supplier of an airbox that fits. My car is an early S4 with the wide S3 radiator.

I have an S3 with the tall block 711M engine and Webers. I got a fiberglass air box from Frank Filicicchia of Famous Franks Lotus parts. It took a bit of fitting, but is larger than the stock box, which means better airflow. Contact him at [email protected] to see if he still offers this. He only had the airbox, so I got the feeding duct, air filter, and bracket to hold it from RD Enterprises.
