“I’m sure it works fine but they should have told people with dobinson snorkels that this filter head will leave a large gap on the snorkel that looks weird. I also did the tape method they mention to do but it still tries to slip off the snorkel tube when you tighten the 3.5 inlet adapter. So now that I’ve spent $200 plus dollars I’ll either have to cut the snorkel tube shorter or grind down the inner tab stops in the filter head to make it not look dumb on the truck. I know they are making it for a wide range or rigs but just some more info for people with the common snorkels would be nice. I can’t imagine that I’m the only one who’s bought this and found this out.”
