Default Spark Plug Advice

Anyone used denso iridiums in their 6cyl?
Was looking at these and was gonna hit buy it now but thought I should ask my fellow forum users for their opinion.

They are a pretty good plug apparently, but if you go to Toyota, and quote that part number, I think youll find they are like $4 a plug, could be worth it to save a few quid.

This is my XY wagon, has been in the in the build section of Xtreme fords.

Its on a rottiserie at the moment, been sandblasted inside outside. Chassis rails moved inboard 3"s each side. Have 15.5"s room there now. Had nice convos to, (Doh stolen now) Have some RRS gear that may go in, brought the cheaper stuff first, lower control arms, billet strut caps, shock tower notch kit. Decided on BBF 557 to be exact, brought plates last night. Have to notch the towers now. Also about to buy a 4" cowl scoop. Need a bare block and power glide to dummy up.

In my opinion cant go to wrong with the motorcraft Iriduim plugs unless it is a fairly heavily modified unit or on gas etc.
At least that way the heatrange will be spot on and the plugs will run clean,
Rather than denso iridium potentially designed and heatranged for different engine...
"Performance" iridiums are a but of a toss in my opinion as any iridium needs smaller gap and more voltage to jump than Standard plugs.
Probably get stronger spark out of standard plugs aka series 1 but trade off need to replace them every 40,000km's

Spend the money you save on a set of good quality leads instead.

There are Denso iridiums made for our cars, plenty of people have run them before (FS5, me).
In saying that I have found no difference between a $120 a set plugs to my now $20 a set plugs.
I get my plug leads from QLD ignition leads. Made to order, 9mm spiral wound core, in any colour, $85, and they will post as well.

In the end with mucking around with plugs for a while ... i ended up going back to standard plugs ... in an EGAS engine.

The reason being there was little to do difference in them ... except the price .... and they are pretty eas to change .. it worked out cheaper to replace standard plugs every 50,000km (I could get actually get that much out of them on LPG) .... than to replace Iridiums every 100,000km .... and sometimes they'd need replacing prior to that.

As for leads ... QLD Ignition leads are excellent as well for the $$$$$.

On both my AUs I use stock NGK plugs and change them once a year. Cheap and easy to do. They both run stock leads also.
