Antigravity Batteries Weight Reduction - Audi S4

Today, I upgraded my S4 replacing the weak stock battery with a lightweight lithium solution from Antigravity. My car is heavily modified and I wanted da bit of a weight reduction. A light weight battery made sense more than removing the rear seats to reduce weight. Although the battery swap was straightforward, the car required adaptation coding to recognize the new battery, a process I performed using VCDS, as shown in the video.

034Motorsport SuperDuper Inlet

This thing is absolutely massive and I'm sure flows very well. This inlet mates up perfectly with the P34, S34 and X34 intakes. It works for the B9 and B.95 S4 & S5 as well as the B9/B9.5 SQ5. The support turbos include the TTE710, TTE810, Pure750 and TS2. This huge inlet should flow very well for that big turbo! The installation is pretty straight forward, but may require a few small tools to reach the inlet fasteners.

034Motorsport Ignition Coils

Today I installed 034 Motorsport red top high output ignition coils and some fresh OEM NGK spark plugs gapped to 0.022". This setup will help support my Stage 3 build with the TTE710 Turbo. The ignition coils are supposed to provide higher output and aesthetics, and fresh plugs gapped down are a good idea for a hybrid turbo build. If your plugs and coils are getting a bit old, this is also a great option for you, but you don't need to gap the plugs down on a stock turbo.

034Motorsport Transmission Mount and Insert

The 034Motorsport Street Density Transmission Mount is a performance upgrade for the factory transmission mount assembly. It replaces the factory mount's soft rubber damping medium with a high durometer rubber, which provides better support at higher power levels. This mount is a direct, drop-in replacement that limits unwanted transmission movement and improves performance. 034 also offers a billet aluminum Transmission Mount Insert that can be used with the upgraded mount to further improve performance. This insert fits into the large void in the factory transmission mount, limiting transmission movement without sacrificing ride quality or increasing NVH.

Soft99 Brake Dust Cleaner Challenge

Soft99 Brake Dust Cleaner is a product that promises to remove brake dust from wheels. But does it really work? I put this cleaner to the test against the stubborn and excessive brake dust of my Audi S4. My car turns its wheels charcoal gray before it can chew through a tank of E85.

Fuel-It! Bluetooth Flex-Fuel Analyzer

I decided to convert my 2018 Audi S4 (B9) to E85 to boost performance. E85 is a high-octane fuel that can provide significant power gains in turbocharged engines. It is also very inexpensive, cheaper than 93 octane gasoline. The results of my E85 conversion have been impressive with 034 Motorsport's excellent E85 tune. My S4 has shown a big improvement in 1/4 mile runs and I'm down to just 3.46s accelerating 0-60! However, E85 ethanol content must be verified to ensure that your tune can support it. In my case I chose to use the Fuel-It! Flex Fuel analyzer paired with my iPhone.
