im upgrading to ngk iridiumix plugs and im stage 1 tuned if that makes any difference, does anyone know what to gap them to or do they come pre gapped? thank you.
Just purchased NGK IRIDIUM BKR7EIX for my newly tuned MK6 GTI. I'm seeing conflicting gap sizes on GTI forums. Some people are recommending 0.028 for stage 1, others are recommending 0.032. What would you recommend?
I need recommendations for a spark plug for hot, humid weather. I also need info on the plug gap, as I haven't been able to find anything on the other forums.
Any body know the recommended gap and spark plugs for a 300 hp 08 Legacy GT on E85??
I am trying to make a spark gap Tesla coil that will have a capacitor bank being supplied ≤25kv since it will be on a spark gap Tesla coil, it will be charging and discharging a lot of times per second. For this specific type of application, would ceramic or polypropylene capacitors be better in terms of lifespan and ability to get maximum power through the coil. Thanks in advance:)
i am changing out the sparkplugs on my 2012 2.0 skyactiv mazda 3, i cannot find the right gap size to set them at, they are preset at .052 but that is not correct. the owners manual online says .030 - .033 but that seems way to small to me. and others online are saying .040 to .044. does anybody know the correct number for the spark plug gap for this engine?
I've been chasing an issue that acted like a vacuum leak for a little while (stumbling while cold or at wot) and finally checked my plugs after getting a p0300 random misfire code. turns out whoever installed the plugs didn't re gap them. they're covered in oil and gapped at 0.035 which is nooo bueno since im running 20-21 lbs of boost. I'm a bit of a noob so now I'm paranoid and just wanted to ask if running too big a gap for a while could have done any damage?
Anyone know what the gap in spark plugs is supposed be for a 2008 subaru Impreza sedan? I've found some articles but they all give a different answer
Okay I’m sorry if this is a question asked a lot but I cannot find a page that has one answer on this so I figured this would be quicker.
I have a bone stock 2015 focus st that has some negative ignition correction (some dips down to-4, and highest I’ve seen is +4) I was going to change the plugs because the cars at almost 60k and I doubt they have ever been changed so I think that’s what’s causing this issue.
But what gap do I get!!! I’ve seen anywhere between .3 - .36. I’m not sure what to get. I’ve already decided to get ngk iridiums.
A while ago I made a [continuous spark gap circuit] (https://www.reddit.com/r/electronics/comments/hjtvqx/astable_555_driving_an_ignition_coil_to_make_a/?utm_medium=android_app&utm_source=share) from an astable 555 and an automotive ignition coil. It worked pretty well, with continuous arcs of about 2cm. Schematic here.
I want to make the circuit smaller and lighter, so I'll need an alternative to the ignition coil. I bought one of these small transformers online, but the arcs were tiny and it barely tickled my hand.
I'm not sure whether I should keep searching for a better transformer or just build some kind of voltage multiplier to boost the arcs. I also hear some talk of flyback transformers and ZVS circuits for big arcs, any suggestions?
I have a $800 1996 Geo Prizm 1.8L that I am only using to learn manual transmission. It has a rough idle that got a lot better after I swapped out the god knows how old air filter that was disintegrating. I also measured the spark plug gap and it is 0.050 and supposed to be 0.031. These are likely the original spark plugs on the vehicle, which had over 162k miles when I bought it and I've driven it less than 30 miles. Should I replace the spark plugs for about $10 (for all 4 with copper spark plugs)?

When the switch is pressed down, then current is allowed to flow through and create the spark. But what is the switch doing to complete the circuit?
If you see at 3:17, he manually connects the wires to the battery to complete the circuit which then generates the spark.
Same with at 4:31, the two wires are put together to complete the circuit, and the sparks occur.
Then he decides to implement a switch where he can press a key down instead. See the first link.
But when the key is pressed down, it doesn't look like anything changes as in no wire or component is moved. It's especially confusing because when the wires are first clipped to the key, no spark is generated either. So is the key operating on something that's not seen in the video?
What is the key doing here to allow the current through?
