Speedriven S65 Billet Anti-surge Valve (BOV)
Speedriven replaces the factory plastic diverter valve found in the V12 biturbo Mercedes with high-quality billet aluminum parts that are machined from aircraft-grade material and are direct, bolt-on replacements for the factory BOVs (which are made of plastic). Once installed, they offer superior durability compared to the factory units, while also serving to give your twin-turbo Mercedes’ engine bay a more aggressive look and that sought-after "turbo sound".
We've also made them significantly easier to install than the factory 3-bolt BOVs by doubling the number of holes- allowing you to assemble your BOVs and align them properly without fighting spring pressure during install. You can read more about why 6 holes are better than 3 here: http://speedriven.wpengine.com/2015/...les-v-6-holes/
Better sound, better quality, and easier installation for $250. Can't beat that, right? Except, you can- because we're still offering our 10% off summer pricing on all billet parts, making these $225 per set, shipped anywhere in the continental US.
