just installed trick flow plenum and K&N fipk attached all hoses wispering sound under load
is this normal? idles perfectly runs strongly did miss a vacuum hose or what?
yea, some intake noises are normal. Double check the vaccum hose on the back, and the ones on the front and that all the bolts to the lower plenum are snug. if it all checks out then your good.
Trickflow plenums are a bit noisy from my experience
