ECS Tuning Intercooler & Charge Pipes

Heat kills performance. Today we will upgrade my 2018 Audi S4 (B9 3.0L V6 TFSI) with a shiny new Front Mount Intercooler from ECS Tuning. Intercoolers are essentially heat exchangers for compressed air generated by a turbo or supercharger. Our S4s are turbocharged from the factory and make lots of heat. Combined with tunes, hybrid turbo upgrades and full frame builds the amount of heat created can be astounding. The factory FMIC was just too small to deal with these heat levels, especially in hot climates.

Audi S4 Active Exhaust Rattle Fix

Many B9 S4s are experiencing an annoying exhaust rattle related to the active exhaust system. Some S4s, like mine, even throw fault codes including P0477, P0475, and P049F showing there is a problem with the valves. This is often caused by a weak or broken spring inside the exhaust door control unit. Interestingly Dodge Charger and Challenger models have the same Küster brand actuators flaps/valves inside their exhaust too. Facing the same issues a newer spring has been made available by Mopar that eliminates the rattle.

ECS Tuning X-Pipe - Audi B9 S4

I've been looking for some options to spice up my S4 exhaust. There are several X-Pipe / resonator delete kits on the market. Today we test out the ECS Tuning B9 S4 3.0T Center X-Pipe kit. I will show you how to perform the installation and we will compare the sound against a stock exhaust. Will this be a horrible mess of drone or will this be an amazingly cheap way to get sound from your S4?

034 Motorsport P34 Intake Kit

Today our 2018 Audi S4 gets its first performance modification. We will be installing the 034 Motorsport P34 cold air intake kit and getting rid of the stock air box. The premise is cooler charge air, more noise and better performance. The stock airbox works hard to silence the turbo to the point that it's very hard to hear. With the 034 kit the sound is a huge upgrade. We're able to hear the turbo flutter and spool under idle revs. When driving the turbo spool and whine is excellent under load. It sounds amazing and everyone who rides in the car loves it. We will be doing more modifications to this S4 and performance testing it!

Audi S4 Brake Flush

Today I will show you the easiest way to DIY a brake fluid flush on a 2018 Audi S4/S5 B9. The power brake bleeding method is by far the quickest, least messy and most sure way to flush your brakes. Per the Audi maintenance schedule brakes should be flushed every 20,000 miles or 2 years. While this may seem like a frequent interval fresh fluid and elimination of air in brake lines is essential to optimal braking performance.
