Went out to the Denso WEB site and there is no listing of plugs for the 05 or 06 MINI. The 04 MINI has the IK20 listed with the gap preset from their factory .032. There must be a reason that the vendor has not listed them for the 05/06 models......

If the vendor is not recommending them, it is probably a good idea not to use them.

The Denso's come pre gapped so no need to worry about that. If you've never used them, you'll understand why you can't gap them once you see one.

I've been using the 22's for a couple years now and can say they're a great plug.

Find IK20 for $42 including shipping on EBAY. The plugs were listed for an Acura. This is my second set, the first set was bought for the MINI, same packaging same gap, same plugs.

IK20 on EBAY, buy it now price $32.99 + $7

Search Ebay Motors using "Denso Iridium IK20".

These would be the correct ones?

The Results of the research are as follows

These are for the 2003 Mini Cooper
NGK IX iridium 6418 BKR6EIX 0.032$6.95
And These would be for the 2003 Mini Cooper "S"
NGK IX iridium 6441 ZFR6FIX-11 0.045Supercharged$6.95

Found it difficult to research the Denso IK-20's The Denso web page would not offer up the part # or price and as you can see stated that the gap was .044 for the Cooper and the Cooper "S" The part # may be IK20 for the Cooper and IK22 for the Cooper "S". I just couldn't verify it.

YearMakeModelEngineIr PowerGap2003MINICOOPER1.6 L - L40.044 2003MINICOOPER S1.6 L - L40.044

Essentially Iridium is Iridium is Iridium and the NGK's seem to run cheaper.

True, the NGK's are a little cheaper than the Denso. However, the electrode on the Denso is 0.4mm and the electrode on the NGK is 0.6mm. I've used both and prefer the Denso's.

I guess most what i find disturbing is the disparity in gaps between the NGK's and the Densos

I've got the Denso IK20s in the mail.

http://cgi.ebay.com/ebaymotors/ws/eB...MEWN%3AIT&rd=1

So are they pre-gapped? No messing with gap? For sure? ok...

And torqued to 22 ft lbs? for sure? alright...

So basically the IK20 is only one specific kind of plug. ALL IK20s come with the same gap, specs, etc... There are not different kinds of IK20 plugs with different gaps, etc... right? seems to make sense but u never know with some companies...

Any comments are welcome!

I think the IK22 are the commonly recommended colder plugs for a reduced s/c pulley. But some don't change the plugs at all.

yup. Ik 22 is the right one ,and they come pregapped.Check the torque often as they are known to loosen and eventually blow.

Denso doesn't offer plugs for th elater MINI's because they changed the gap on them in 05. The same plug will work just fine, the gap change is prolly done for emission purposes.

Iridium plugs are not to be gapped. The tip can and will be damaged if gapped. (read, DO NOT GAP THE DENSO IRIDIUMS)

22's would be a colder plug than 20's, so increased boost for an MCS or increased compression would be a reason to run them. Otherwise, you might get a noticable random miss at idle speeds. The colder plugs have a tendancy to detonate LESS than a warmer plug, although, if not needed, they will also foul out easier than the hotter plug. The hotter plug gets hotter than the cooler plug, therefore allowing the carbon deposits that build up to burn off. The boosted or higher compression engines have hotter cylinder pressures, therefore benefitting from a cooler plug.

Currently running IK24s. Brrrr really cold.

My Cosworth MTH load has a ton of timing & the 24s seem just fine.

As you could expect they don't like to idle for long, but they sure hold down the detonation above 7000 with California's crap gas.

These are not the plugs for everyone, but they do work great on a highly modded setup.

Original plugs in my 2003 MC CVT were BKR6EQUP
Replaced them at 36k with ZFR6F-11's - ca $2 ea. - smoothed out the idle and drivability.

I imagine MINI/BMW chose the 4 prong plug so they could claim 100k service.

Great, but we are in the non-S forum, so any answers to my questions are welcome.

For a regular justacooper MC, 2005, 5 spd, not supercharged:

Denso Iridium IK20, standard gap from the plug factory, torqued to 22 ft lbs.

Is this correct?

I apologize for posting in the non-s forum, I just saw the title of the thread and not the forum it came from.

MC Power forever

To stirr the pot a bit...

I'm running IK-24s right now. These run even cooler than the IK-22s. The idea behind cooler plugs is to get more heat out of the combustion chamber to fight timing retard. the 91 octane CA gas isn't that good, and every bit helps.....

As for torques, I've used 18 ft lbs, the Bentley manual says 20. But at 20 the head sure feels soft..... 22 would scare me a bit.

And for gapping, you CAN gap a denso plug. Just be VERY CAREFULL and use a wire plug gauge, not the feeler gauge types... My 24s came at 0.065 or MORE out of the box, so I regapped them to .045 or .055, I don't remember which....

And I too bought from that eBay store... Under $40 shipped, can't be beat! Some places want to charge well over $15 per plug, before tax and shipping!

Matt

The reason for switching to the $10.00/each Denso plugs is.................?

If there is an actual performance gain, $40 is cheap, if not, I'll go for the $2.00 plugs.
