id like to see what differences the coil would make on a SOHC. granted it wont make much more hp, but it will help throttle response and the idle.

if it shows an improvement, this will be on the list of items to be done on the ranger when it needs a tune up (50,000 miles)...

the stock coil for the SOHC and the OHV are the same parts....they have the same Motorcraft part #'s.........

i would be willing to bet that it would also improve the throttle response.....i know the idle on the SOHC's are better and smoother than the OHV's.......

yea......Wayne told me that all the Explorer people that he has sold them to haven't gapped out their plugs so he has no data on the SOHC's......

hopefully Rick keeps us updated on the SOHC install and gives good data for the SOHC....

Coil & Wires, coils in, truck runs with the drivers side wires done, can't even get to the passenger side. Dealership will do the plugs & it looks like the passenger side wires.

Rick
jack up the front end, remove the passenger side wheel and try getting to the plugs from there.

Be careful with the SOHC plugs, they are platinum and you can damage them during the gapping procedure!!!

Leaving stock gap wont hurt anything, but the whole point to the coil pack is being able to regap them allowing them to burn all the fuel making your truck more effiecent. You should still see a slight difference with the coil pack anyway...
