Spark plugs

[wild_one]

I've had a 'skim' around and couldn't find what I'm looking for. I would like to stick some plugs in my 2009 1.6 zetec S. As usual there is a selection of possibilites on the parts sites. Could someone point me towards an online source that gives a definitive plug choice regardless of the Manufacturer?

Thanks for the reply. Yeah, the big box shifters like ECP etc all have a selection of plug options. I was wondering what the ‘definitive’ correct plug is? And gap?

[Bobr]

I think the gap is 0.7mm.

So, the Ford manual says 0.7-0.8mm gap and torque to 15nm. The NGK plugs are gapped at 1.1mm and tightened hand tight then 2/3rds of a turn? Should I reduce the gap or leave the plugs as they came in the box?

What is the part number for the NGK plugs? If there is a number on the end then it means the gap is preset. Gaps would be different depending on the manufacturer.

The NGK catalogue lists TR5B-13 or LTR5IX-11
