I installed a Wix 24801 air filter dP gauge on my new 3.5L Duratec Taurus. My (reasonably) new filter exhibits a vacuum of 11" after a couple of WOT runs. https:/
The product is actually made by Donaldson; the little paper of install instructions references Donaldson by name.
The gauge goes up to 25" and then would indicate a change is due. I'm not sure if the 25" value is sane or not; these are generic and not specific to any application.
I am also considering installing one on my 6.2L F250 gas truck as well.
I'm open to suggestions; at what vacuum would I consider an air filter change, and why? State your value and reason behind the suggestion, please. Would it be the same for each engine, or different? www.amazon.com/ WIX-Filters-24801-Filter-Service/ dp/ B0014BI1KA
