Ravi decided he was going to choose violence with me again over the weekend. So Im making this just to remind him violence isn’t the answer.

This manifold will allow you to run external cooler. If there’s enough interest we will make an external air to air and air to water core with plumbing.

This will work on all s58 and b58 vehicles. There will be a few tweaks, but for those interested. DM for presale purchases.

Msrp $3250
Presale $1999.99

Thanks

Shoutout to Rick for breaking into the 7s with his G80 M3! His car showcases the power of restraint; you don’t need over-the-top mods to be fast. Rick's dedication to gradual upgrades has paid off, and we're proud to have been part of the process.

Congrats to and the team!
