Well,just got my TRD cold air intake today and will install by next week.Has anybody put TRD CAI in there 08 sequoia 5.7L?......Any difference on gas mileage and sound of the engine?...Cant't wait to put it on but the dealer can not put it on till next friday because there main TRD mechanic for that dealer is on vacation

.Do not want to put it myself because I do not want my warranty getting voided.My sequoia only have 1,200Miles on it.
