VRP Billet Surge Tanks (M113k)

Elevate Your M113K with Style and Performance

Upgrade your M113K with the VRP Billet Surge Tank, crafted for maximum performance and sleek aesthetics. These polished billet aluminum surge tanks combine advanced engineering with cutting-edge design to enhance your engine’s efficiency and appearance.

Key Features:

• Innovative Design: The VRP Billet Surge Tanks are a testament to VRP’s commitment to enhancing the M113K platform. Each tank is crafted from high-quality billet aluminum, ensuring durability and a striking polished finish.
• Enhanced Flow: Unlike factory tanks, our custom surge tanks are hollow throughout. This design reduces restriction and improves laminar flow, leading to increased power output for your engine.
• Adjustable Fitment: The two-piece design allows the surge tanks to rotate 180 degrees. This feature ensures compatibility with top-mount intercoolers and various custom setups, providing flexibility during installation.
• Easy Installation: These surge tanks are direct-fit and bolt-on upgrades. Installation is straightforward, making it a hassle-free enhancement for your vehicle.

A TUNE IS REQUIRED WITH THIS PRODUCT.

• For an even easier installation experience, we offer a gasket set for these tanks as well. You have the option to use RTV instead, but RTV does make removal and reinstallation much more difficult.
• To make these tanks, we had to develop custom-reinforced couplers. After 4 iterations we settled on 5 steel rings to keep them from collapsing due to the vacuum. These couplers are REQUIRED to run these tanks unless you are running it in the forward position with top mount coolers.

Our CLS55 saw gains of 31WHP and 10WTQ upon installation of just the Billet Surge Tanks!

Stock Tanks: 463.3 WHP / 581 WTQ

Billet Surge Tank: 494.6 WHP / 591 WTQ

• We are at *6600ft elevation running on 91 octane. Results will be even better for those at lower altitudes.
• The only change made between runs was the installation of the tanks and the REQUIRED reflash using the same tuner. You will need to tune for these due to the significant increase in air intake. Grab the tune here.
• No log tuning, no dyno tuning, 31WHP gains on a canned tune only!
