The CarBole DG508 kit supplies eight high-resistance coils with curved boots that match OE-style fitment for many pre-2004 Ford E- and F-series vehicles and select Lincoln\/Mercury models. These coils are corrosion-resistant, abrasion-resistant and built to tolerate high temperatures and electrical load typical of heavy-duty use.\u003c\/p\u003e\n\n\u003ch3\u003eWill these coils fit my Ford or Lincoln engine?\u003c\/h3\u003e\n\u003cp\u003eThe DG508 kit fits a range of 4.6L, 5.4L and 6.8L V8\/V10 engines used in Ford E150\/E250\/E550 and F150\/F250\/F550 models as well as compatible Lincoln and Mercury vehicles—except certain 2004-and-newer F150 5.4L applications where straight boots are required.
