“As good as K/N for the FL5
No need to spend $500+ on a cold air intake , OEM setup is great on the FL5.
With the addition of the PRL definitely a significant increase in wastegate noise when you let off the throttle and filtration remains good enough just change your oil regularly and you won't have a problem.
Slight increase in acceleration from a standstill but because the FL5 is so heavy it's not a very noticeable amount.
Good upgrade for those who want to stay stock but want a bit more noise.
Do recommend the PRL or the K/N panel filter for the FL5.”
