DIY spark plug change

I've used the 'rubber tube on the top of the plug' for years on plugs I can't start using my fingers. Never crossthreaded a plug.

To improve your hoover push a length of narrow plastic tubing into the crevice tool & seal with masking tape/electrical tape. Again, something I was shown a long time ago!

Thanks, good tips there!

I didn't use a rubber hose, but just the plug socket and extension bar. Used the method, as suggested above, of rotating counter-clockwise until it falls into the thread which worked a treat. Took a couple of goes to make sure.

I bought a feeler gauge to make sure the gaps where good. The NGK plugs came pre gapped to 0.8mm, which I checked with the gauge, and they were bang on. I contacted Hyundai to ensure I had the correct gap - 0.8 to 0.9mm, so no issue there.

Kudos to Hyundai's live chat contact function on their website btw. Asked the question and got a response very quickly. They were able to give me the correct gap and torque settings for the plugs.

I've used a foot pump or bike stirrup pump with a football needle in to make a useful 'air duster' in the absence of a compressor.
