My 2001 QX4 VIN# JNRDR09Y11W210086 the door has 8/00 manufactured date, Can you tell me what part number for my #1 and #6 ignition coil?

I have Beck/Arnley 178-8360 replaced #1 and Beck/Arnley 178-8362 replaced #4, but the Nissian part that comes out has Hanshin MCP-2850 22448-4W011 I checked the net and it seems 22448-4W010 is for my 8/00 build and 22448-4W011 is for 9/00 onwards. I am confused if my P1320 is caused by these Beck/Arnley coils.

Can you help? Tia

The #1 and #4 that came out should have been different part numbers. #2-#6 are the same, #1 is different.

It's also quite possible that the later coils will work just fine on an earlier truck. I always had the impression that the
change was to improve reliability.

Going to order the Hitichi parts which states up to 8/00 today, just want to make sure. They are more expensive than the ones 9/00
onwards.

#1: 22448-4W000
#2-6: 22448-4W010
FAST also says to refer to TSB ITB02-020 but that's just for static in the audio system caused by the ignition coils.

Sorry for the delay, had to acquire an Infiniti FAST disc.

Parts arrived. 22448-4W000 is a Hitachi part IGC0022 on the box. Coil itself has no marking except IGC0022 Made in Japan. A dot is also found on top. 22448-4W010 is a Hanshin part MCP-2850 also a dot is found on top.

#1 replaced (easy one)
#4 replaced, took a while since a lot has to be removed. The old #4 tip looks brownish and smell of gas, checked the spark plug, nothing seems wrong, not sure what happened. replaced the coil and reset code with my USB OBDII , hoping P1320 will not come back so I can take the emission test tomorrow.

Update, passed emission test.
