Spark plugs

[iamdub]

Ok! Thanks! Good to know. Yeah I was noticing the prices and thought it was really cheap. Like 90$ for plugs and wires

That ~$50 you're saving may very well cost you thousands. I bought my NGKs back around the end of 2019 off ebay. I had the seller email me current/actual pics of the plugs in the listing: Pics of the two 4-pack boxes, the individual boxes and of the plugs themselves.

Curiously, ACDelco and RockAuto do not list that plug for an LQ4. They recommend the 41-962/19299585 Double Platinum as the OE plug.

They also show the old school R44LTSM/19354418 and the ACDelco Professional 19307137 Rapidfire. All with a .040 Gap.

As Chris stated, be VERY cautious buying from Amazon, Amazon sellers and from ebay as counterfeits abound and they are wrecking engines. I'd recommend a dealership, Summit Racing or Rock Auto, the latter being my usual first choice.

Hey question for you. Somewhat on the same topic. How often would you recommend tune ups? I have NO check engine lights but am thinking about doing a minor before the winter. Spark plugs etc…. Thanks

Well, the Iridium plugs are good for 100K miles. One of my wires fell apart after 50K miles. So I reckon we'll go to 50K or 75K mile intervals from now on and continue with the annual checks. We pull a plug on each side once a year.

Any way to determine knock-offs vs actual NGKs? I run amazon TR55 or TR6s and always buy from amazon but they are clearly labeled as NGKs and the box looks legit. Haven't ever had issues and I buy the cheap copper ones. Usually less than $20 for a set of 8.

The point of cheap counterfeits is to be able to produce them cheaply enough that a profit can still be made even when selling it much cheaper than the genuine version. This requires sub-par manufacturing methods and materials, even down to box quality and the print quality of the box labels.

All you gotta know is what the real stuff looks like:

Dang after watching both videos I want to pull a few plugs and inspect them closely. Crazy how good the counterfeits are!
