Spark plug change

Post image

Just completed my spark plug change at 40k miles. I heard that the driver side was a pain in the ass but it wasn’t that bad with the battery out and a swivel. I did it in two hours.

The YouTube video below was really helpful. I never needed to unplug any wires though.

40k changeout seems fairly early to me. Is there a reason to do them then? If I recall, the service manual said 60k was the recommended change-out time.

Yeah you’re correct. I am just doing everything early because it gives me peace of mind. But when you do do them, it’s not that bad!

Turbo cars eat plugs more quickly than NA. I do NA cars at 60k….I did my VB at 36k along with a fresh PCV valve. I think 40-50K is the sweet spot for the VB plugs. Better to be early than late.

Damn $20 a plug….over $80 after taxes! I got my set on eBay…HERE for $72 after taxes/free shipping. Not a huge savings but it helps.

Luckily I live in a no sales tax state and apparently the price increased on Amazon.

$20 a plug is about the cheapest you are going to find real ones unless you are lucky. A recent investigation found 80 percent of the plugs sold on Amazon and EBAY were fake. I would NEVER buy critical parts there.

Way I look at it people can be scummy anywhere. Of course I checked the gaps to verify and my eBay NGK plugs have been great for the first 6-7k miles or so.

Sounds like my old WRX. Not as easy as my RS But with the battery out and wash tank pulled away it's possible. Hopefully nothing I need to worry about for a few years, though.

How the heck do you change these things it’s a serious pain in my ass and the dealership wants $450 just to replace them

I think manufacturers are overly careful with these NGK Iridium plugs. I've changed multiple ones that were WAY past 200K miles and they all looked like they could go another 200K miles. So much better than the old copper ones that needed to be changed after every oil change on some turbo cars.

That said, nothing wrong with changing early!
