DIY Spark plug purchasing. 75% cheaper than Mazda
 

Mazda Australia would prefer to insult us all with a retail price of near $100 per spark plug.

Found this place in the USA that sells them at a less offensive price.

$US80 = complete set of 4-plugs (plus postage)

Do not buy from a STEALERSHIP. Get the identical plug from this company at sparkplugs.com

I am kind of getting sick of people constantly whinging about Mazda prices. So you found a better price - congratulations.

are the denso ones better than the NKG ones?

I believe the Denso plugs are hardier and less prone to the effects of detonation then the NGK ones , even though they are dearer they still represent excellent value compared to Mazdas local rip off price :spank:

Great post Dave .............DMRH...:) :lol:

Interesting thing is that manufacturers/dealers appear to have the stranglehold on Denso car plugs in Australia.

Dave, while I agree 100% with the point you make (and I reckon everyone here does as well), if you go on and on about the same thing, you just lose peoples interest. A simple "Stealership $500...XYZ link $80" would get more attention.

I can sticky this if you make a nice title for it Dave.

There is also much cheaper to buy NGK iridium and NGK racing sourcing from Japan. I am going to do so in the next month or so to keep as a replacement set.

I'm sorta with Dave on this one.... It might be a little repetitive, but I still appreciate getting links on cheap parts.
I'm pretty fed up with Mazda dealerships raping me. Now that my baby is ou of warranty, I doubt they will much more out of me.
Thanks for the link, I just purchased a set of Denso plugs due to that link. I didn't realise that Eurocars hit me with $450 when they changed my plugs last time. And they weren't even due to be changed cos I'd had the new plugs installed 10K earlier due to the hard start recall.

PerformanceLub sells them for $140 for a pair of leading and trailing plugs, NGK Laser Iridium. Harold is the man to speak to. I've purchased other stuffs from him and very happy with the products.

I'm not sure though if a pair of leading & trailing plugs means 4 plugs in total, or just 2.

Wow, that's actually cheap.

Anyone been able to test out the laser iridiums and see how they wear?

Great find... always nice to hear ways to save money. :)

BTW how much did postage end up being?

Also Taka, are you going to just source your spark plugs from japanparts.com?

Not sure.
I may want to source it directly from NGK rather than via Fujita.

Anyone aware of a heat ranges comparison chart between NGK and Denso?

...it proves my memory serves correctly :D

Interesting. But many of us don't have your facility in Japanese or Chinese. Kannst Du mal uebersetzen?

Taka, in a nutshell can we put some meaning to the chart...?

you guys should also check out Mazsport for plugs
US$54 for a full set of aftermarket NGKs - I think I've seen them even cheaper than that elsewhere as well .

Oh sorry.

Andrew asked me to post the chart of conversion numbers

HKS heat number 25 = Denso heat number 16 and NGK heat number 5 .... so on and on

Thanks taka. And the reason I asked was I ordered the Denso ones and they are 27,31.

Brettus, the problem with Mazsport is (the last I looked) its a lot harder to order stuff from them than most other places. So unless they have updated their site, I doubt anyone is going to use them for everyday items like spark plugs.

not sure what you mean - click the box put in you credit card no. etc and job is done - what is hard about that ?

hmm, I wonder if the NGK RE9B-T and RE7C-L refers to the heat number, if yes, then it's lower than denso? is that better or worse or ?

lol thats not hard at all, in fact I would love to be able to get to the point where I have selected a product and can enter a CC number, but go to http://www.mazsport.com and click products....Nothing to buy, nor any services, etc, etc.

Cheers

ahhhhhh -I see zee problem now - wrong Mazsport

http://mazsport.net/store/

2 mazsports?????

lol you know I didnt even notice the "Seven Hills, Australia" ! doh!

Ohh well I know now ;)

OK confused. The Spark Plugs site shows the Denso plugs should have a gap of 0.035" AND 0.044". I have checked mine and they are at 0.035", is there any benefit from going to 0.044" (considering the OEM plugs are gapped to 0.048")?

Cheers
