On3 Performance 4″ Diesel Large Urethane Air Filter Element – AF4 - AF4
You can shop quality on air filters all over the place and you will not
find a better unit than we offer. These are not cheap because they are
made to handle a turbocharged application. What happens when you cheap
out? Your filter will fall apart from the inside, parts go into your turbo
and cost your BIG MONEY in the end. Do not cheap out on this part, I
promise you, it will cost you money and we see it happen all the time
