I have been told…. Use Champions?

I have always used NGK plugs and plug caps since running a Suzuki TS50ER (restricted, but unrestricted to 42mph back in the day). An RD125DX, a GT250, a GSX750, a ZXR750H2 and a GSXR1000K3 followed… all on NGK. Even the current Husaberg TE300 runs NGKs. The Hilux and Landcruisers don’t count as they are running the Devil’s Urine as a fuel.

However I’m told Rover V8s prefer Champion plugs over NGK? Resistance within the plug? What is the Landyzone view on this? What do V8 people choose as their spark plug of choice?

As an aside, I like the NGK ‘no nipple on the spark plug tip’ and the plug cap clicking on. The connections using the ‘nipple on’ seem less secure? Thoughts?
 
Oooooo, hold on. I search for ‘spark plug’ but I have now found this old timer…

 
I've had dozens of various Land Rovers vehicles with V8's in them. For the love of God please don't waste your money on Champion plugs. The quality is terrible in my experience.
I only fit NGK, or Denso.
Get a set NGK BCP6ES for a road car or BCP5ES (like me) for my Land Rover that never sees the motorway. The 5's run slightly hotter and stay clean even with the low rev life the Landy has.
The "C" in the part number means the plug has a 5/8" hex which is smaller than normal and I find they're easier to handle and fit, especially if your V8 is an early model.
 
The car came with a set of Champions in, and a new set of 8x N9YC Champions plus a new set of 8x BPR8ES. I did a plug change to the new champions (no difference to the misfire at high revs / under load) and yesterday changed to the NGKs.

It didn’t want to tick over when cold on the NGKs but after a couple of gentle blips, it was fine at tickover. Misfire still there as before (I have my money of the distributor cap and rotor being the culprit, should be here in a couple of days).
 
NGK. I've never had trouble with them. Dad used to have a marine shop and used many, many thousands. Had one faulty one, ever.

I run NGK in my VWs and the Disco 1 (actually, everything, in honesty 🤣 )

High RPM misfire can be a worn cam too, if it comes across like like rough running and sudden power tapering off. If it's a hard misfire on a single cylinder, more likely an ignition issue, but then you tend to get some popping or backfiring from ignition is the exhaust system.

i had a very worn cam (in the end) it presented as popping under acceleration.it was actually blowback into the inlet when the inlet valve opened, as the exhaust valve wasnt opening
 
The misfire has suddenly started, but I don’t disagree it could be the cam. Looking at changing that in the next 6 months.

The engine starts and ticks over beautifully. Just bad misfire in the top third of the rev range and poor power (compared to a couple of weeks ago) plus engine running slightly hotter. Plugs are very dark when pulled out. It is now popping and banging on over run in the exhaust.

Some background, it is a Rhino Charge car and running std distributor with an RPi Amp2 wired in a cool spot in the bay. Large K&N air filter and open (side exit) pipes. It was running fine until the alternator pulley broke and the belt came off.


At that point I did take the distributor cap off as the vacuum adv/retard thingy was hanging off. Fixed that and did not remove the distr, just the cap. However it is in a poor state internally so waiting for a new cap to arrive.
 
Strange how people's experience varies, even those owning the same make/type of engines.
I've used Champions in a variety of cars, not just 4x4's, for decades & can't remember ever having a problem though admittedly the recommended replacement interval of 12k may be shorter than modern plugs from different manufs.

My RRC V8 doesn't currently use Champs. as NGK's were fitted at last year's service carried out by my Indie. & I've no intention of changing them just for the sake of it.

nb. you can't always trust a well known name for all their products. Guided by NGK's reputation for spark plugs I had the garage fit one of their crank position sensors to my old 5 series .. it lasted less than a month :oops:
