Review on Spectre Performance Air Intake Kit SPE-9918 for 2009-2014 CADILLAC/CHEVROLET/GMC: High-Performance, Horsepower-Boosting Upgrade (Escalade, Suburban, Tahoe, Avalanche, Silverado, Yukon, Sierra) by Loren Jacobson

Double checked to make sure it fits 09 Yukon Denali and even the manufacturers website says it fits, got it and installed and after finishing and closing the hood it didn't closed. closed so had to slam which is very unusual for me then I noticed there was a heck of a big gap on the side of the airbox which I noticed but didn't think about when my wife said something so I'll give her one Rating I gave, I even asked for help a few days ago from the help tab which sent me to the manufacturer's website and got no response, sent three emails and got no response and they were spaced sent by several weeks to give time for you to get and still nothing go with k&n kr another brand with better customer service, i emailed a competitor for heat shield info and received an email within a few days from them and from there the sizes do not work
