Technical TwinAir which spark plugs and gapping?

[Didge3]

Hi,

Anyone know specifically which spark plugs the Twinair uses and what gap is correct? So far I can only find reference to NGK ILKR9G8 (97168).

Thanks

Not off the top of my head but I do know they are pre gapped. No gap adjustment needed.

The car in question is 2013..

Most posts seem to mention NGK as above

Go on either the ngk or Denso plug finder page?
Maybe Denso VXUH22 £18.94 for 2 on Ebay
Ngk above seems correct for 84 bhp and 102 bhp 64 is different
NGK seem to be £30 a pair

Don't gap them sure the twin air uses iridium plugs which can be damaged by checking the gap

Some caution against even checking the gap, as this can cause a hairline fracture leading to the extremely brittle tip breaking off inside the cylinder. Whatever, handle these plugs with great care, and if you drop one on a hard floor, put it straight into the bin. Under no circumstances ever use a ball type gapping tool.

I would also recommend some anti seize on the threads and using a torque wrench to install them?

Anti seize, definitely. Ensure you choose something that's safe for use with lambda sensors.

The required torque for fitting the plugs is very low, and there is a risk of overtightening if using a torque wrench, particularly a full size one. A safer way, particularly if the plug washer is new, is to angle tighten them.

Video here from Phil on the Panda page. My mate (not the same Phil) told me as iridium long life plugs if starts and runs fine leave existing ones where they are.

Now that's one strange plug socket

What appears to be the best plug key for these is the Laser 3682.
It's 250mm long, 3/8 drive magnetic plug socket that fits perfectly down the small holes the plugs are fitted.

Anything fatter and shorter just won't fit and as it's magnetic, you won't have trouble fishing them out of the holes after.

A normal socket with a long extension works fine as well
