Spark plug Bosch or OEM FORD

i have been using the W7DTC plugs and they have been working great for me..my car is always held way up in the rpms..they have never fouled out or caused me any problems..and i get 8 of them for 30 CDN... seat of the pants tells me i like them better than my old platnums..the car idles better with them.. they are worth a try

I've been running W7DTC's for about a year now, with no problems. I haven't done any back-to-back dyno testing to see the difference between them and the usual W7DC's, so I can't comment on any power losses/gains.

I have never had an issue with the Bosch's

I personally pick the Bosch Super Plus Copper because they are cheap and last about 20-40k miles...

I'm running bosch platinum single pronges with no problem..

im running reg bosch silvers (of course the right heat range) on my supercharged setup and they run perfectttt, no misfires or anything, i love bosch plugs

They have 2 electrode and yttrium content with copper core. First, the car idle better now than with USED NGK 3 prong spark plug.The idle is lower at 800rpm(new spark plu gap) compared to 920 with NGK (bigger gap) The stock spark plugs were hafl used, white-black color but with some yellow tiny dots on electrode surface whats this ???? I went for a run and these spark plug are not made for high rpm use.. The engine noise is metallic above 4k and it doesnt pull like used but in shape NGK plugs. The spark plug gap is too small I think. I will check my mpg and report this later.

I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak

After I put them in (I was one of the first in my region to carry them and use them in my own car) I found a significant loss of power. Swapped those puppies out for some Bosch Supers and I was back to where I was before I put the Plats in.

Don't use those, they suck. The center electrode is tiny, and fouls easily. I've had problems with them, and so have others. They don't last for ****.
