I did this on a single cylinder golf cart engine, no difference in power but a noticeable increase idle smoothness and part throttle drivability. Basically smoother running. Im satisfied with that.
@AmritGrewal31 I knew how it ran before, I don't "sorta think" it runs better now I "Know" it runs smoother, doesn't jerk as much off idle to slow driving each time it fires, singles tend to jerk at low rpm, now I "think" it does better on fuel but no real evidence.
very cool. never heard of this before...Once we get the gti back from the alignment shop, we'll be side gapping those plugs ASAP! Thanks for the video!
What do you make of those plugs with 3 or 4 electrodes? They're technically side gaped too. I can't remember why I did it but I snapped 2 of the 3 electrodes off mine years ago, I'd probably seen a similar video on tuning the old briggs and stratton engines for go kart racing. Great channel by the way, thanks for all the teachings.
Thanks, technically they are but you can't gap them, and the plug is designed for longitivity so the spark will take the path of least resistance and with three prongs has more paths to take so when one bit wears etc it'll find another path
I’ve used Bosch triple electrode plugs on my 16v since 1996, modified 1.8 kjet with 2L block, gas flowed head and manifolds, they have been faultless and I’ve had good power on the rolling road, they were also OEM plugs afaik. I can see the theory behind side gapping a single electrode plug but can’t see any advantage over the triple design, in fact only drawbacks
The triple design was designed for longitivity and just provides more options for the spark to jump. Yes, they work, but they also can't be gapped correctly.
Spend the time and read the documented tests that have been done. Doing this isn't a 10bhp mod. it's being able to improve the burn rate of the intake mixture which then improves the combustion process
Some times increasing spark , like putting in colder plugs or boosting up the coil to get a bigger cold burn can increase cylinder head temperature as the fuel entering the head does help cool it , So be careful when not sticking to manufacturer specs
@GreyGooseRestorations I can't find either of those brands in stock anywhere, heritage parts has some "OE" ones made by BBT. Where would you buy them from?
Gawd, that's a horrible combustion chamber design. I could see how "side Gapping" your plugs would try to help a chamber with no squish and huge deep flat roof. Why not run an NGK JRXC type plug thoug? Side gapped X2.

Are you sure it not just placebo?
No when you research it it's proven to improve things

Awesome video! I learnt something new today 🙂 I am curious to give a go on my car. (MX5)

Dyno vs theories, it tells the truth
I agree. All bullish:t unless paper proof

cheap feeler gauges have sharp edges and give incorrect readings. sand the edges with 1500 grit paper
Good vid I will be doing this for sure,
Can you recommend me some ht leads for the 16v please, iv been looking to buy some new ones but undecided 🤔
Thanks, beru or bosch for leads, worth paying out for top quality but don't fall into the trap of these "uprated" ones 👍

Id buy from autodoc just checked and they have NGK and magneti marelli both top brands
How often would you replace them?
Every year at least, but depending on miles twice

Looks like a Dremel job..😂😂 with that one can buy a complete range of fancy plugs if you look hard enough..
