I have both vehicles and assume they are the same but want to confirm.
Thanks. |

NGK Laser Platinum Part Number: PTR5F-11 , stock # 6579, Gap .044
NGK Laser Platinum® Spark Plugs I am using the iridiums. |
Any thoughts on the following?
NGK Part #6579 PTR5F11 Laser Platinum: $9.70 NGK Part #7397 Iridium IX: $6.51 NGK Part #6044 ITR5F13 Laser Iridium: $9.87 NGK Part #90813 Laser Iridium: $5.65 The #90813 Laser Iridiums seemed like a god price so I contacted NGK and asked the following: VehicleType: Car Make: Mazda Model: 6 Year: 2005 and 2006 models Engine Type: 3.0 L V6 Comments: A major online auto parts retailer lists two different NGK Laser Iridium spark plugs for my application. The part numbers are 6044 and 90813. The features listed are identical: Information for NGK 6044 Laser Iridium Laser Iridium? spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions ? Laser welded Iridium center electrode tip ? Platinum disc welded to backside of ground electrode provides long life ? Trivalent Metal Plating for superior anti-corrosion and anti-seizing ? Tapered ground electrode to minimize quenching ? Consistent and stable spark ? Faster starts and quicker acceleration ? Better fuel economy and lower emissions Information for NGK 90813 Laser Iridium Laser Iridium? spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions ? Laser welded Iridium center electrode tip ? Platinum disc welded to backside of ground electrode provides long life ? Trivalent Metal Plating for superior anti-corrosion and anti-seizing ? Tapered ground electrode to minimize quenching ? Consistent and stable spark ? Faster starts and quicker acceleration ? Better fuel economy and lower emissions However, part number 6044 is priced 58% higher. Can you tell me if there is a significant difference between these two spark plugs and if both are suitable for my application? Thank you. NGK's response: Hello, The new number for this application is a 90813. As far as the precious metal types and the configuration the two are the same. As far as the price is concerned I am not sure as I do not handle pricing. Best Regards, Jason Norwood NGK Spark Plugs ( USA) Inc.

I am currently using: NGK iridium # TR5IX, # 7397, .6mm tip. Got these installed Feb 2013. Love them. I however am using some rather hi potent Accel Ignition Coils as well. Accel part # 140032 (2 Valve for Mustang---reverse wires going in to coils and re-use stock Mazda boots). The 2V coils are angled a bit and slightly hit on back of intake plenum---can be remedied by cutting off top part with side cutters---these have hold-downs but wires need to be reversed--tricky to do but possible---the 4V MUSTANG coils aren't angled and fit better but you need to make a hold-down (last pic).
I like my current iridium ones because of the 6mm tip, i am leary of a smaller tip, especially with the hi power I currently have. No misfires here! https://www.mazdaforum.com/forum/mem...ked-b-2174.jpg http://i1049.photobucket.com/albums/...oilNewTop1.jpg http://i1049.photobucket.com/albums/...ilsX3White.jpg http://i1049.photobucket.com/albums/...structions.jpg http://i1049.photobucket.com/albums/...eforeAfter.jpg http://i1049.photobucket.com/albums/...sSideCoils.jpg http://i1049.photobucket.com/albums/.../HoldDown4.jpg |
Both of my 6s are bone stock. $5.65 ea. For iridium plugs is a good price. Also, NGK didn’t reveal any differences between the #6044 and #90813 PNs so that may be the way I go on the next tune up.

The spark plug gap on the 90813 is .052. Adjusting the plug gap on an iridium plug is a no-no! .052 is a big gap for an old worn out stock ignition coil. I would not put a large gap plug on an old worn out ign coil! Click on NGK site and do your own search, I did and it came up origianlly around .044 gap as per previous post. SEE specs: NGK 90813 TR5AI-13 Spark Plug The 6044 has a gap of .051 SEE specs: NGK 6044 ITR5F-13 Iridium Spark Plug My 7397 has a gap of .040 SEE specs: NGK 7397 TR5IX Iridium Spark Plug |
Agreed. .052" is too wide of a gap for an OEM coil to jump. Thanks for the heads up.
