vs
Spark plug BERU or OEM Mazda
I'm pretty sure that modern Mazda's do do this, only not in the situation you're describing. They use it for their stop start system to save having to fit a beefier starter motor and what not, simply inject an extra dose of fuel and fire the spark plug to get the engine going again.
Pros: saves beefier starter motor
Vehicle:
Mazda 6
I have the beru side firing and they work just fine.
Pros: work just fine
Ours has been pretty reliable, had some issues with odd stalling once which was cured with new plugs/wires/carbon cleaning, rear shocks just went recently.
Pros: cured stalling issues
Cons: rear shocks went recently
Vehicle:
Mazda 5
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 use Beru Utra-X UXF79 4 tips plugs. It's a great plug for my chipped B6.
Pros: great plug for chipped engine
Vehicle:
Audi A4
Part number: UXF79
I would call New Dimensions... but I decided to go with the Beru Ultra-X. These have 4 nodes instead of just 1 on the head of the spark plug. They are awesome!
Pros: awesome, 4 nodes
Beru Silverstone all the way....Spendy, but worth it, totally. I have taken the pplugs out a couple of times since I put them in a little more than a year ago, and have found very clean plugs, no fouling at all. the electrodes were in the same shape as when I bought them, hardly worn down at all.
Pros: very clean plugs, no fouling, hardly worn
Cons: Spendy, but worth it
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
