I have one on my 05 ,very easy install, read the filter specs and it matched or exceeded everyone elses I looked at , the price may be a little high , paid about $200 for mine from " ALL ABOUT DIESELS" ,maybe its higher for your year truck , I can't see the price difference either,, I was ready to buy a Volant system priior to finding this one,, I think their website is --- allaboutdiesels.com,,,,,,,,,,had mine delivered in a couple of days
