I saw a topic about the sparks for the A-series, especially the tuned. Anyone (I don't know why) have tried same NGK-sparks with deeper threaded rod, and guess what... With the normal NGK-spars he have 66 hp at the flywheel. When he replaced the plugs with the same type NGK-sparks, but with a deeper threaded rod. All in one hour, he have 74 hp's at the flywheel, W00T!!!
That's good value for you money dude, hardly what I'd call. Surely of brobdingnagian value, because the sparks costs each cheap ass 3 pound and you get
12%$ more power! *melonsing* 12%
So, I have this type NGK-spark in my standard 1275 engine: http://www.jamestown...ct.do?pid=9511#
These sparks are already 6 months plugged in my 1275 A+. I cannot pass 5500rpm. Mkay, I could live with it because it's a old engine who needs a thoroughgoing revision.
When I saw the NGK bougies at a pump station, the NGK B6ES: http://www.kaboodle....k-plug-ngk-b6es i thought, let's give a try. When I pull the V-Power sparks, they looked good. Light-brown at the circles. The spark was really in a good condition. And I plugged the B6ES-plugs.
what the hell? The engine revving very facile. On work temperature, I pulled the standard Metro engine easily to 6500 rpm.
And i stopped with pulling, because the valve springs are 100% standard. I cannot believe, only the sparks are replaced, and now I'm in a really another world. How can this happen? It's a simple technique between the plugs, which was meant to make really a diminutive difference.
Now I want to revise my engine with stage 3 head and SW5. I saw there are more than 100 different NGK-spark plugs. I've sought in Vizards manual for tuning the A-series, but he says nothing about the sparks plugs.
The questions:
- Which NGK-bougies are amazing for 1275 and more? Especially in the low range rpm.
- Which length of threaded rod is ideal?
- What means the codes, like B6ES and BPR8ES? What means the numbers? I want to know.
