I cant remember, is it possible to pull just one sparkplug to check?

Dealership quoted $900 for the sparkplug change, I've got 160,000 miles on my 2014 AWD 3.8. Never changed plugs. Is it possible to just pull one plug to check, or are they all buried?

I can't answer your question but that is a lot of miles on plugs. I'd talk to an independent shop and get a price.

I know, but my last Genesis, a 2012 3.8 had 138,000 miles and I pulled the plugs and they were fine, I felt like I was wasting my time!

Just because the "look" fine, doesn't mean they are. Over time, material wears off on the spark plug head and the components encased in the metal housing get damaged from residual heat/cool cycles of the engine head. The longest I'd ever go is 120,000miles. Spark plugs are cheap compared to an engine. NGK Iridium Spark Plugs are $11/piece.

I was about to say that sure, it's easy to get to three of them. However, at 160K miles if you have to ask, you possibly won't be able to get one out without doing damage. This is one of the few cases that $900 is a decent price for that job, if it includes them fixing anything that goes wrong in the attempt to get those plugs out.

Also, there' no need to look first. You need new plugs, there is no question.

I just cracked 100K w/ my 2015 5.0. Just got all my service parts together (plugs, trans pan/filter & fluid) for my indie shop to install.

I would definitely check prices at an independent shop. I paid $530 for plugs AND serpentine belt for my 4.6 at a local shop. The car was running great. More of a... 'just should be done' maintenance at 150k miles.
I'm sure prices vary per region of the country.

 

[glennk]

Congrats! Sounds like you have had an uneventful 100k.

Yeah screw that. Just order the plugs online and do it yourself. 30 min job prob cost $50.

Call an independent shop. They may do it for one hour labor. If you have the tools and the time, do it yourself. Each plug runs about $11/piece. OE's are around $16/piece. 18851-11070 - Spark Plug - 2012-2017 Hyundai | hyundaiparts

Iridium iX® vs. OE Iridium Spark Plugs​

NGK builds two types of iridium spark plugs: OE Iridium and Iridium iX®. Every plug in the Laser Series was designed for an OEM application. All dual precious metal plugs are designed to provide maximum longevity. For the OE Iridium series, dual precious metal means iridium on the center tip and platinum on the ground electrode. Some of these plugs have special resistors or multiple ground electrodes, depending on the original equipment requirements.
The Iridium iX® spark plugs are a single precious metal aftermarket performance plug. They are a great option for modified engines, and where recommended, are appropriate replacements for OEM spark plugs. Iridium iX® plugs are an excellent upgrade from standard nickel plugs. The Iridium iX® plugs are offered in various heat ranges and sizes to fit most automotive and non-automotive applications.
These two plugs perform similarly, due to their fine-wire tip design, but the service interval is different; the Laser Series are typically designed to last 80 to 100 thousand miles, where as the Iridium iX® spark plugs are designed to last 40 to 50 thousand miles.

Laser Series is the OEM equivalent for Hyundai spark plugs.

Well, at 160,000 miles you're due - this just came out of my 5.0 @ 100,400 mi. Mine were roasted. I can't even feel it idle now!
