They’ve been in development for a while but the new Summit Max Efi Ls intakes are out! The taller profile ones have longer runners and more plenum volume (9.7L) than typical sheet metal Ls intakes. Mid and short profile, Rectangle and Cathedral, Black or polished, 92 or 102mm Tb versions. Better mixture distribution and performed well in our testing. $499 (with fuel rails) introductory price too!
if you go into the photos, check out the 360 view and you can see the runners and bells extending up into the plenum rather than cut-off at the surface. The plenum material is thicker than what’s commonly used so good for boost!

Good point. Thank you. I rarely post in externals and the people we communicate with usually need us in internals. Folks, we have questions answered in Gen. 3/4 internals if you are curious about the conversations.
