Thread: Spark plugs & oil

Hi All,
digging up an old thread I know, but rather than start a whole new one...

Just wanted to say that I put some new plugs in my '00 Thor P38 on the weekend, maybe it's just me, but it already feels a lot smoother...

Anyway, I used Bosch Platinum Plus FR7DPX. These were the same as the old ones anyway so I thought they will do the trick. They cost me $6.50 each from Repco (usually $8, also available from supercheap) Compared to about $25+ each for the champions, or $20 each for Denso, I figure this is a bargain! I asked the Repco bloke why they are so much cheaper, he reckons Bosch sell at least 10 times more plugs than the rest and can therefore be cheaper... Don't know about that...
Anyway, I reckon I got a bargain, time will tell me if I did or not

I recently replaced my plugs from ngk's to britpart jobbies that came in a service kit from the uk, my engine idled smooth beforehand (30,000kms on standard ngk plugs), now it misses every now and then on idle... Ngk have my vote!

onya Keithy - makes me feel better about the NGK PFR5G-11 "Laser Platinum Premium" plugs that have been in my '99 Thor for almost 3 years and still don't miss a beat. At $26 each, they'd better be good

I agree, ngk have always been in my engines, although I've just bought a D-max (settle down, its the mrs' new 4wd haha) so no sparkies in that! I should have left them in there, they were all still perfect... Shame I didn't keep any of them, if it ain't broke...

Ebay.uk absolute cheapest for iridium plugs about $90 delivered, got them in my '01 hse on gas.

I can't seem to find any evidence that iridium plugs are any better than platinum, except that they last longer with platinum lasting 60,000 MILES and iridium lasting 100,000MILES that's a huge difference... but so what? plugs are not that hard to change...

So why would one pay $25 dollars a piece compared to $8?

Have I made a "mistake" with the $6.50 Bosch platinums?

'cos I like to test stuff out, and I'm a mug

If the $6.50 Bosch plugs are rated for the P38 I am sure they will be fine. Let us know how they are doing after a couple of thousand Kms.

Cheers, Paul.

Well BOSCH is one of the leading ignition manufactures out there, so not suprised to hear that they sell 10 more than the rest. However i have the standard NGK plugs which are now due for replacement, and might try the iridium ones.
