Volant 151536 PowerCore Cool Air Intake System - High Performance Cold Air Intake Kit for Trucks & SUVs - Improves Horsepower & Fuel Efficiency - Perfect for Off-Roading & Daily Driving

I purchased the Volant 151536 PowerCore intake system for my 2007 silverado classic style crew cab truck, and you should too. This system is CARB certified (stickers included), looks good with new style black top air box, came with new style PowerCore style maintenance free filter, install was a breeze maybe 30 minutes, and that's only because I dropped one of the mass airflow sensor screws in the motor misplacing it. Lol be very careful with these as new OEM replacement cost will set you back 80 bucks. Fitment was perfect no issue with screws on the bottom of the air box as others have stated in their reviews. This should also fit a number of other 2003-2007 GM 4.8, 5.3 Vortec 1500, 2500 applications. Performance gains were noticeable however it doesn't feel like manufacture claimed 5-10% or 38+ HP although I don't cruise around at 5300 rpm's so maybe it does. Last thing worth mentioning is the increased sound. In my opinion no difference at normal economy cruising, but does get a bit annoying admitted throttle. Guess I'll just need to drop a magna flow muffler on the truck to drown out the sound for my next mod.
