Spark plugs for M3 2007 2.0 L

[bashmohandes]

Please help if you can,
I am trying to find what NGK spark plugs would work for a mazda 3 2007 2.0L.
I need another option than the iridium ( ILTR5A-13G).
I want to go copper or Platinum but i don't know what is the part number. Any help is appreciated. ( NGK is preferrable)
For some reason the 2007 & 2006 part numbers are different from 2005 & 2004.

Cheers,

I have an 2006 M3 2.0. On the 50K kms. mark, I've changed my spark plug to,
Bosch Platinum 2 – part number HGR8MDP or 4315, cost me around $ 6.00 a piece.

Also found some post that you can substitute the OEM Iridiums to a different ones such as,
NGK Copper Spark Plug TR55 / TR5 / TR6
Bosch PlatinumIR Fusion – HGR8MQI or 4515
Bosch Platinum 4 – Bosch 4488
Champion Double Platinum - RE7PYP6 or 7437

I suggest that you make a search just to obtain a common consensus just to be certain. Check too from the manufacturers website for the latest part numbers.

The above part numbers are for reference only, I will not be held responsible and liable for any curcumstances that will occur after installing such plugs to your vehicle.

I wouldnt suggest copper spark plugs at all. When I bought my car, I told the mechanics at the used car lot to change the spark plugs and they gave me back the old OEM iridium ones that were in the car. I didnt know they had put in copper spark plugs so I was running the car for months not knowing why it felt like it was lacking in power (lagging, stalling). Had Karen and her tech team at Agincourt Mazda switch out my spark plugs for me to OEM iridium ones and honestly, it runs SO MUCH BETTER than it did when it was running on copper spark plugs. I ended up giving Karen a call back after two minutes of driving my car after it was serviced because I was pleasantly surprised with the increase of power in terms of the car.

I was also told you can switch out the plugs to platinum ones but I just decided to go the OEM iridium route since I couldn't convince my dad to put in the NGK platinum ones I had ordered.

how come you guys are changing spark plugs soo early? dont you usually do it after 4 years or 100k?

[TheMAN]

right, there's no need to change plugs so early with this car... they can easily last 120k

bosch plugs are crap and NEVER run right in any japanese car... I've seen the electrodes break off too... japanese cars like only NGK or denso spark plugs... don't be cheap and pay the extra few bucks for the right stuff for the car

I aleady have 99K on my Car
I went with the Champion Copper plugs
P/N RS12YC for 4.99 $ a pair from CT
I have put 2500 Km on them so far, no problems
I know they won't last as long as the iridium and i will possibly have to change them after 20K
Gas mileage still the same
When i pulled the original spark plugs from the car , they were in a good condition, no visible signs of wear or damage. I probably have changed the plugs prematurely, but at 99K i didn't want to leave them anymore.
