Hello!...

...I am seeking assistance regarding a problem I faced today concerning the availability of some spark plugs with the following specs:

Thread: 14mm

Reach: 25mm (or 1 inch)

Seat: Tappered

Hex: 16mm

Heat range: NGK: 8 or 9
Champion: C59 or C57
Bosch: 5 or 4 or 3
Denso: 27

Anyone knows where I can find some good quality spark plugs for a Zetec E (2.0 lt / ST 170) based-engine with the above specs?

Thanks in advance for your time!
