So..after hours of cross referencing, checking, triple checking..I believe I have a solution for those looking for a performance based ignition coil, that will fit under the coil covers, and is offered by conventional performance suppliers. Now I may be wrong as it is still untested, but uf553 coils (found in EcoBoost v6's) the 2 prong versions...are looking like they will work, resistance is correct... length is damn near spot on...still unsure if they will bolt down with existing hole...but their also the type that the body of the coil protrudes down in to the plug well...and there fore if they work will be a very clean looking install. And msd and accel make nice high output versions. Am going to try and find a stock one at the wrecker and test my theory..but..I think I may be on to something....thoughts?
