2014 R-Spec 5.0 spark plug change

How were you able to reach into the tight area where cylinder #8 is and get the plugs out? The driver side high pressure fuel pump makes it physically impossible to get the 18mm socket on the bolt.

I honestly do not remember having that much of an issue. Can you use a swivel or crows foot to get to it?

I just did my 2014 Hyundai Genesis R-SPEC spark plugs this last weekend with the OEM NGK's. Pretty straightforward, but I recommend using a 1/4" set for the 10mm coil bolt on the driver side back plug with a swivel, it was more difficult to get on without removing anything else. The remainder were relatively easy with some swivels and a locking extension for the plug socket. My plugs were late to be changed at 139k, but overall not in bad shape.

I used a magnetic 10mm bit to pull the 10mm coil bolts once they were fully loose, which helped not drop the bolts into the abyss.

I could not find a specific torque guideline from Hyundai, so I used the NGK range and set them at 11-11.5 lb ft

If I remember I'll post pics of the old ones, worn but definitely functional.
