Another Instant-Muscle Shield fresh from the #skunkworks. Check out this beauty for a #LS3 stock intake manifold. Now we just need to find someone brave enough to test it for us and flog the wee out of their ride!This should be available in late November, earlier if we can get some good testing and data back quickly on it!

We will be working hard on more in the months to come. What would you guys like to see us do next?

Part # 140021!
