Sparkplugs change

[Mo Ali]

Hi everyone,

I have a 2018 Toyota Yaris hybrid and am due for an oil change. I've been doing some research on car maintenance and came across the recommendation to change spark plugs regularly.
 

1. I'm wondering how often should spark plugs be changed in a Toyota Yaris hybrid

2.What kind of spark plugs should I get?

Any suggestions would be greatly appreciated!

Milage please ???

60k miles change intervals 

Spark plugs best to use only original Toyota bought from a dealer only. 
Other sellers may sell you fake plugs .

Tony, this is nonsense.  You can buy both NGK or Denso at any reputable distributor and places like Eurocarparts online.

I don’t think it’s a nonsense, quite opposite I would say, but we all have our own thoughts. 
The price difference between Denso or NGK plugs bought from third party traders is minimal £40-£45 vs £47 original Toyota plugs from a dealer. 
Made by Denso again, but the problem is that there are many copies out there and sometimes difficult to spot. To avoid buying fake plugs best practice imo is oem Toyota only from a dealer. £5-10 more won’t hurt anyone’s pocket.

My Gen.3 had its spark plugs replaced at 60k miles.

It is a requirement that they are Iridium. To use anything else will damage the engine/electronics. I strongly recommend getting them from a Toyota dealer.

Cutting corners on critical items to save a buck seems like madness to me.

[anchorman]

Who says that corners will be cut by not getting them from Toyota.  I’ve fitted literally thousands of sets of plugs in my life and never once have I obtained fake plugs and never once in the dozens of sets I’ve fitted to Toyota’s have I bought a set from Toyota.  I’m. Not suggesting for one second that people shouldn’t but there definitely isn’t a need to buy them from a dealer to avoid fakes.  It’s an utterly ridiculous notion.

Mo Ali.

Theres a member on here called Parts King.  If you want genuine parts and I’m not suggesting for one minute you shouldn’t, he works for a dealer and if you message him, he will post them to your house.   That will make it easy to get the right stuff and ease the fear raised by these nonsensical claims.

Really, how's that?

I’ve sold from my small family business of 30 shops thousands and thousands of Ngk Bosch and denso , I’d have to really try to get fakes and then cataloging them so they fit but at a later date obviously fail , it’s fair easy for my shops to sell right first time ,that and we’re in ex Pitt villages so a bad rep would probably involve violence of some kind

Wow... I hit a nerve there.

I didn't mean you *had* to buy from Toyota, but the way the OP read he was looking for "alternatives" to save money, rather than buying the correct genuine parts.

Many years ago I knew of someone that used to import fake car parts from Spain which were then sold on to Dealerships!  Ryanair have recently discovered fake, supposedly genuine parts in some of their aircraft engines. I'm not saying Toyota plugs would be fake of course!

Just to throw my hat in the ring, I owned a Volvo once and had to order a part, while waiting at the parts counter, I leaned over the counter only to see a pile on euro car parts on the floor, just because it's from the dealer doesn't always mean it's genuine, unless it's a dealer part  only, water hose etc.

[Stivino]

Just because it's a Volvo dealer doesn't mean they don't repair other marques.

Those parts could have been for anything.

[wildtapholer]

Could be but would you send your Toyota to a Volvo main dealer to get serviced, I don't think so, plus the amount of parts behind the counter were enormous.

Just because you go to a main dealer, don't think every part will be genuine.

[Yugguy1970]

Dunno about dealers but I used to use these https://www.i-r-s.uk/ to service my cars when I had 2nd hand, they're Renault specialists but can do most work on most cars, expecially routine servicing.

[TonyHSD]

Agreed. 
All main dealers around the world at some point may use non original aftermarket parts for one reason or another. Some even replace oem supply parts with local products, for example some Mitsubishi dealers back in the days where these cars were popular here in UK they were offering Belts for their cars in white boxes and made by Gates uk, and not original Japanese Mitsuboshi - the oem supplied belts at that time. 
This is not an issue as long as is mentioned to the customer because obviously when a car been sent to a dealer for service and repairs we all expect only original parts and quality workmanship, however in real world this is not always the case. 
For the plugs , bought directly from an official dealer oem Toyota plugs very unlikely to be fake, or if they turn to be than you are covered.
If you buy from your local car parts shop for example you can buy non original aftermarket good quality plugs like Denso, NGK, Bosch, Beru, just make sure these traders are good men and does not trade fake parts, like that well know man from eBay.
And remember, original parts like plugs in oem boxes or other oem parts does not worth buying from non official dealers. The profits on these are very low and a real traders does not make much money as they do by selling aftermarket’s, oem parts max profit 5-10% for the.independent trader, where aftermarket can reach up to 45% or even more . You do the maths

You can take your car anywhere you want to have it serviced.

I served my apprenticeship in a Vauxhall dealership, but that doesn't mean I can only service Vauxhalls, or that I can only repair Vauxhalls during the course of my career.

[wildtapholer]

I think your missing the point, yes any garage can service your car, the point I was making, Volvo wasn't using always using genuine parts and a lot of other garages don't always use genuine parts, but I can't see any garages  flogging fake plugs.

[Yugguy1970]

It depends what you mean by "genuine".    When I serviced my own cars, if the dealer parts were too expensive I'd search up who made them, get the manufacturer part number and often find the same part would also supplied to other car makers.  Except those makers were less "premium" so the parts cost less.

You find this espeically with car groups.  Don't buy "Audi" brake pads", get Seat ones for less.
