Denso IRIDIUM PART #? for the MSP

[leosilva79]

Hey there guys I have searched and searched for the exact part # for the Denso Iridium spark plugs for the MSP. I have gone to sparkplugs.com and Densos website and they don't list anything for the 2003 MSP but only for the 2002 MP3. I have also searched on the forum but did not get an exact number for the MSP only the MP3. I would like to know what is the exact model # that will fit a 2003.5 MSP for the Denso Iridium spark plugs.

Thanks,

LEO

but why?

 

[leosilva79]

why not.. there are some members here running them and have had good results and i thought of trying them out.

I thought the consensus is that copper are better for our cars than the iridium. Is there a reason that you want to choose iridium over copper?

I really like the white speed in your sig and avatar.

Well personally after reading the lengthy information on Densos website about their Iridium plugs, and reading what others had to say on the web and on this forum I have decided to try them out. They have several advantages:

More info on the following can be found here: http://www.denso.co.jp/PLUG/iridium-e/index.html

1) Iridium center electrode is of 0.4 mm in diameter= less resistance to create a spark. This would also lower the required voltage and improve firing performance.

2) Denso uses an all-round laser welding to ensure a highly reliable joining on the electrode itself= Being that this is made of Iridium it has a much higher melting point than that of Platinum therefore conventional welding would not work too well. So instead Denso uses an All-round laser welding that melts the iridium and provides a much better weld point and spark is consistent well under heavy driving conditions.

3) The electrode tip is not made of pure Iridium= this makes it less prone to corrosion than pure Iridium.

EtcEtc.. This is all a personal point of view and I am not saying that iridium is better than copper or platinum. I am simply stating a personal point of view!


I am not stating that NGK sucks... I love NGK I have always used them in the past. But I love trying new things and this is one of them.

Thanks for the comments on the Sig. Its all done in Photoshop... since there are no white MSPs I made one for myself!

I think i just found them.... based on the quote from the reps at NGK... link here: http://www.mazdamp3.com/vbb230/showthread.php?s=&threadid=27354&highlight=ngk+quote

I did a cross reference # from the NGK model #BKR7EIX-11 to the Densos and got this:

http://www.iridiumpower.com/crossreference.php

and if you go here you can see a more detailed explanation of the model # and specs: http://www.iridiumpower.com/sparkplugspecs.php

Then just look for the IK22 model # and there you go!

also to see all this go to: http://www.iridiumpower.com/index.php

I knew that for the 02 MP3 took the Denso IK20 and since the 02 MP3 does not have a factory Turbo it would not work for the 03 MSP. Because of this i felt the need to find the right part number which is IK22 for the MSP with a 0.8mm or 0.032 in gap. This is based on the NGK part Number cross reference running a colder plug of 11.

Thanks to all for taking the time read this thread

give us an update with results after you have them installed =)

 

[leosilva79]

Zray I sure will... im about to go to Autozone and pick some up. I was there yesterday night but they had no idea what a MSP was and they were telling me that Bosch was the best one for my car. So i needed to find out on my own what the part # was for the Denso. The cool thing is that they carry them in stock so you don't have to order them online

of course Denson will try to make you belive their plugs are the best thing that ever happened to cars. They are trying to sell their product.

I'm not sure what the heat retention qualities are for Iridium plugs, but copper is a lot better than platinum, as far as heat retention, as copper sheds heat easier, and therefor is better for turbo apps. Who knows. =)

 

[leosilva79]

03MSPRO its true, most manufacturers will claim several things that make themselves seem better, and I agree lots of them do that. I still feel that I should give them a try based on actual people that tested them and found them to work out quite well.

Until I try them I can't tell you their definitely better. And if they are it should be so minimal that it be not as noticeable. But hey what the heck (shrug).

sweet old bump.

I am trying to reach Denso and am now wating on a call back with the specific recomended model # just to make sure that the Ik22 are the right type!

 

[leosilva79]

I just installed the plugs today... and wow the idle and acceleration feels a lot smoother.. power throughout the gears feels silky smooth and helps a lot with the hesitation. A great product to get a bit on the expensive side but well woth the money if you ask me!
