vs
Spark plug Motorcraft or BERU
Reviews
I however replaced mine with motorcraft and do not have pinging anymore but still run 91 octane as 93 isn’t common in socal.
Pros: no pinging anymore
On any of the gas trucks with the "modular" engine family (4.2 V-6 and 4.6/5.4 V-8) it seems like if you use anything other than Motorcraft spark plugs and coil packs, the engine won't run right at all, no matter the brand.
Cons: engine won't run right
Vehicle:
Ford
I've been using beru rs7 plugs without any issues.
Pros: no issues
I always stick with Motorcraft double platinum, or Autolites if they aren't available. No reason to get fancy with sparkplugs.
Pros: reliable, good quality
Yup, these are great. Just be sure you gap them to APR's recommended gap of 0.024" ±0.002" or 0.6mm ±0.05mm. If you want 1 step colder plugs, not needed on your setup, but if you do for the future in Stage 2+. For 10$ more than the OEM NGK you can get the BERU.
Pros: great, step colder plugs
I have the beru side firing and they work just fine.
Pros: work just fine
I got a Ford, so I use Motorcraft. They work great.
Pros: they work great
Vehicle:
Ford
I've had much success with BERU plugs on all of my VW's, especially my 16V's. Beru maks the stock/replacement plugs for Porsche, VW and Audi (I work at a Porsche dealership, I see it all the time)
Pros: success with BERU plugs
Vehicle:
Volkswagen
I swapped out the oem plugs for Beru rs7 plugs when I went APR stage 2 at ~3k miles. The car ran well. Fast forward to the present with over 18k miles and is20 swap, and I noticed a few stumbles at idle. Nothing major but I figured I'd change them since APR recommends 10-15k mile intervals (visually the Beru plugs looked fine).
Pros: car ran well
Cons: stumbles at idle
Mileage: 18000 km
i've had the beru ultra x's in for about 8K...no problems...no noticeable improvement either...starts the same (good), runs smooth...no complaints, but no better than stock...
Pros: runs smooth, no problems
Cons: no improvement
Mileage: 8000 km
