I have always used Riffraff's boots on my ford they have the best quality and last the longest!!!

Boots are of great quality, and they won't break the bank! Plus, You can order them in several colors to match or contrast with your truck/under hood theme. These are so much better than the stock flimsy wimpy boost leak prone stock silicone boots. I recommend these as an upgrade, even if you have a stock truck. Clay and the Riffraff diesel crew are all great to work with!
