I was doing some spark plug research today and found something very unusual. The IKH01-24 plugs are 4 steps colder than the OEM spec 20 which gives me pause for a daily driver. TRD Japan lists an IKH01-22. Only 2 steps colder. Might be a better choice for our street driven cars.

Lance that's interesting

Are you going to try the TRD version which is only 2 steps colder or the Denso IKH01-24

They're pretty close to the same money. I think the TRD plugs would be better suited to my application, but regardless, they're not going to live as long as the OEM plugs if you're street driving. I just bought a set of Denso OEM plugs from Advance Auto for less than $70 with local pick up (in stock). It's really, really hard to justify $245 for plugs I might be unhappy running. Maybe if I had an extensive track schedule this year, but I don't right now. Lottery hasn't been my friend!

Beside all that, I just dropped $1060 for the parts to do the cam chain replacement to get rid of my start up ticking noise. But oddly enough, when the wife started the car a couple of days ago, I clearly heard an exhaust tick, so I have to decide what to do next with that too. The bane of higher mileage is getting frustrating, but it's hard to complain when I haven't had a car payment for more than 7 years and haven't had to spend any significant money on repairs of any kind.

That's true $245 for plugs is steep indeed! Are the TRD version of the plugs the same price? Where would you source them at?

That's the shipped from Japan price for the TRD plugs.

I didn't do much research on plugs yet but will be swapping them out before winter. What's the consensus on the best plugs for normal street use (day to day driving with a mix of spirited driving here and there)?

OEM Denso plugs. Can't beat them for the daily grind and even light track duty.

Thank you lobuxracer!

OEM is OEM for a reason it seems. This will be the first time in my life that I buy 8 plugs at once

How many KMs on yours? The OEM plugs are good for a lot of KMs so wondering why you are swapping them now?

BlueRCF10

Im at 39,280km (kilometres) and was thinking of changing them out at 50k. Premature, I know lol

05RollaXRS

OK, that makes sense. You are getting up there so yeah, good idea. Mine is at 16,700 KM. Yeah, garage queen I know LOL

BlueRCF10

Very low mileage! That’s excellent. I’m on Canada so we talk in KM.

05RollaXRS

Yeah, I was talking KM.

BlueRCF10

I wish I had your mileage!

05RollaXRS

Yeah, I picked it up at 13,800 KM so I have about 3000 KM put on it in the last two years. These cars are exceptionally well built so you don't have to worry much about mileage other than the normal wear and tear items.
