Hi guys and gals,
Just wondering whether $70 is a good price for a set of 4 BKR6EIX-11 iridium plugs is good. They are NGK IRIDIUM IX plugs...aslo want to confirm that these are the ones to fit into the front of a GR.

Also need some knowledge of the choice of iridium over the normal type. How many k's should I expect etc etc.

Thanks again for all the help in advance,
Tim

the plugs I would be more concerned with are the ones at the back as they are hard to get to...I would do at least every 25k but actually I normally do it every 10-15k cos I can but I think its a bit excessive

Also make sure you have decent leads (not sure about the GR) but as the GPX has ignition coils on the front 3 cyl. with 3 leads to the rear..I had some made for about $100 which are really decent..although some go to the extreem with leads...some decent racing ones will do the trick.

Correct me if I'm wrong.

25k? i thought the point of getting the iridiums was because they last longer so you don't have to change them as often. like 100k at least.... i remember seeing a post somewhere on here about this.

Yeah 100k for the rest of the Japs - us good old aussies & our sh*t quality fuel... leads to all manner of deposits left on the plugs.

ahh... i see... grasshopper now understands.

So do you guys think that is a good price or not?

hey timnkoo, have a look at the group buy forum and compare the prices. if it's a little more expensive than that you'd still have a pretty good deal

I bought 6 PFR7M (Platium) for $108 (18 ea) 1 week ago...if that gives you any idea. I can get BKR7EKC-N (stds) for $12ea.

Timnkoo PMed me for info - I thought my reply would be worthwhile posted up for everyone. Note we are talking GR's here - but good general Spark plug info:

Hey mate,

The actual sizes are identical. The reason that Mitsubishi state 2 different types is beacause of the difficulty in getting at the back ones to change them.
The only difference is that the other type specified are heavier duty & last longer. Now that Iridium & Platinum plugs have become available, you can have a plug that lasts upto 100,000kms. I recommend using Irdidium plugs all round - keep in mind that these new types of plug were not in existance when the FTO motor was designed - another reason the manufacturers recommendation is for a heavier duty normal type plug.

You can tell an NGK Iridium plug by the 'IX' being in the part number.

To me the difference between an Iridium & platinum is irrelevant as I change my plugs every 20,000kms regardless. I use BKR6EIX-11 all round. Great performance & fuel economy & they never foul up. Its worth spending the extra money on things like spark plugs - a full set for me is $110

Here's a comparison chart for you:

Nickel Alloy - Service life 20,000 - 40,000 kms
Benefits - Standard style of spark Plug.

Nickel Alloy (V-Groove) - Service life 20,000 - 40,000 kms
Benefits - Service life Improved ignitability due to sparking at periphery of the electrode

Platinum 0.8 mm dia. - Service life 100,000kms
Benefits - Long service life and even better ignitability due to a small diameter centre electrode

Iridium 0.8 mm dia. - Service life 160,000 kms
Benefits - Extremely long service life. Same level of ignitability 0.8 mm dia. Platinum

Iridium IX 0.6 mm dia. - Service life 60,000 kms
Benefits - Long service life. Same as 0.8 mm dia. of Platinum and extremely good ignitability characteristics. (Better than 0.8 mm dia. platinum or 0.8 mm dia. iridium)

ta dood...I wanted to buy the IX ones but they only had the Platnium ones in stock....nice info...
