Suitable for all 4.0L TFSI engines as installed in the Audi S6, RS6, S7, RS7 and S8. These valve springs have an extra adapted spring rate and ensure a faster and better response behaviour of your 4.0L TFSI engine. The spring retainer made of titanium enable a lighter valve drive, more boost pressure and higher revs are no longer a problem.

More boost pressure or sports camshafts: Now you need our 4.0L sports camshafts valve springs Our sports valve springs are necessary as soon as more boost pressure is driven or when other camshafts are installed.
