Drops right in to the existing DV easily and I’ve noticed an improvement in spool time between shifts and off the line. Also comes with a tasteful little Alta badge that I wish the larger products (intake) came with.

This spring really let's you hear the air relief sound from inside the car vs the stock one.

Changing this spring helps hold boost in between shifts and definitely works.

Car holds boost 10x better. No more surging at half throttle like the factory spring. Holds boost between gears better. Recommend for first modification on stock n18.

Great spring does it’s job! Arrived quick af! But the amount of packaging for this one spring leveled ten acres of amazon rain forrest. Drop that thing in an envelope and call it good homieS!

Doesnt do anything on an auto mini cooper s. There was no improvement in response or boost. The install was difficult as well. It is a very tight fit to get to the screws on the DV.
