750cc - Audi S4/RS6/S6/S8 4.2L V8، Titan 5.6L

The matched set is spot on—all eight flowed identically on the bench, which took the guesswork out of tuning my Titan. Fitment into the stock rails was clean, and the idle settled right after the swap. Couldn't ask for smoother delivery on that 5.6L.

Swapped these into my B6 S4 and the matched set made idle smoothness noticeably better right away. The 750cc flow is plenty for my setup, and after 2,000 miles the fueling trims are still dead consistent.

Installed these in my S4 and immediately noticed smoother idle and throttle response. The matched set really does take the guesswork out of replacing all eight at once.
