These valve springs are a great, cost effective option! These springs boast 30% stiffer spring rate over the stock T7 Springs.
This listing is for 8 springs, a quantity of 2 is needed for a full set of 16.
They are sold as sets of 8 because as a base upgrade, it’s acceptable to use upgraded springs on the intake valves only to help combat valve float from boost pressure.
If valve float from high revving RPMs are your concern, a full set of 16 is the best option.
