favorite spark plug?

[whd507]

I'm at 95k miles and its due for plugs. I'm leaning towards either the stock motorcraft plugs, or denso irridiums.

anybody have opinions on either or both, or somthing else?

thanks for the input.

for stock engine keep the motorcrafts. I would recommend changing them every 60k not 100K.

Denso is a waste of money. Go with the Stock Motorcraft. :argue:

NGK's

TR6's one heat range colder than stock.

TR55's stock heat range.

I went with NGK TR6-IX plugs instead of the motorcrafts because I have a tune. Notice smoother idle as soon it was fired up.

Got them from Advance AutoParts's website http://www.partsamerica.com/ProductDetail.aspx?MfrCode=NGK&MfrPartNumber=3689&CategoryCode=3411I

Paid like $56 and free shipping.

Motorcraft. I change mine every 10k due to little driving, and what driving I do is intense, under a heavy tune, with 114 octane and NOS. Never had an issue with them.

Iridiums are a waste of money at nearly $100 a set. I toasted a set in under 6k.

Member RAY, 'TheDealer', can hook you up wholesale on Motorcraft.
Cooler versions, or stock.;)
