i need some new spark plugs for a 2.0l focus not bug spec or out tho just seen some DENSO IRIDIUM plugs are they any good or should i just get ngk.. or would you recomend something else??

 

denso are excellent plugs, but i wouldnt pay for a set to go into a focus, just a standard decent make will suffice

 

satndard fprd ones mate in my experience on these they don.t seem to like after market plugs for some reason

 

Just don't use BOSCH, can be a nightmare with leakage in the zetec lumps.
Iridiums will make it a bit smoother, especially around idle and when cold I found, but I also use a ACCEL 140018 ignition coil, defo notice a difference over std ford affair, and very similar money too.

ford say to use bosch hr 7 mpp+v with a 1.3 mm gap

 

All I can tell you is after fitting BOSCH plugs bought from Hellfrauds that two out of the 4 were leaking and missing terribly due to this, within 100 miles, they were totally streaked all around the porcelain, upon enquiring with others found it was not an isolated case, I put NGK in and no problem, though I'm sure ford would have been ok too.
I had fitted them to some other zetecs but these took longer to play up, but the odd one did so.

I agree whit tabetha, have the same promlems whit Bosch plugs her. Many of Motorcraft plugs are made by NGK

 

it just said to use them plugs in the manule (my brother has got a 2.0 ltr focus)
i just dont under stand why ford would say to use them if they are crap

 

I've always used Ford's plugs for standard, tuned N/A, and turbo 2.0l Zetec engines. Also no problems at all with their standard leads and coil packs (even with Megasquirt).

Actually not strictly true, I oilled up a hard (FRS) plug after dropping too much oil into a cylinder after a leaky cam cover.

so you wouldnt go with bosch leads??
