APR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application. They run cooler, resist preignition, last longer than other materials with higher melting points, and even require less voltage to produce a strong spark.

034Motorsport Street Density Motor Mounts for the B9/B9.5 Audi A4/A5 2.0 TFSI are a performance upgrade over the factory mounts, and are a suitable OE replacement for B9/B9.5 Audi S4/S5/SQ5 3.0 TFSI and B9/B9.5 Audi RS5 2.9 TFSI. Street Density Motor Mounts are manufactured with 50 durometer rubber to limit unwanted noise and vibration transfer into the cabin. Street Density Motor Mounts are void-free and fluid-free, eliminating the slop and excess movement associated with the factory mounts, resulting in improved shifting feel and driving dynamics while greatly improving long term durability and longevity.

Note: This mount has two different applications that are based on engine size (Street Density for 4-cyl 2.0T FSI and OE Replacement for 6-cyl 3.0T TFSI or 2.9 TFSI). Please see the Fitment Guide tab below for application information.
