What are the differences between the 3 Nissan spark plugs?

22401-1P1S4VW
22401-1P1S5VW
22401-1P1S6VW

and which one do you recommend?

Thanks!

BTW, if anyone else needs these, I found these at a OKC Nissan dealership online for $8.58/each (www.nissanautoparts.com).

I went to www.nissanautoparts.com and plugged in your part numbers... the response was No Such Part.

 

The 1P1S4VWs are a slightly hotter plug, the 1P1S5VWs are stock, and the 1P1S6VWs are a slightly colder plug. Using the 5s should be fine.

PS DBM - The part numbers are correct.

 

Try inputting those again. It worked for me after a couple of trys.

 

Daniel,

The part number "order" on that database is xxxxx - xxxxx.

However, appending the "VW" on the end allows the part number and price to come up.

Must be an exception to the rule.

 

the other guy is rite. 1st one is slightly hotter, 3rd one is slightly colder. go wit the slightly colder one.

 

Thanks for the tip. I discovered that I had a trailing blank following the VW. That was enough to cause the www.nissanautoparts.com software to choke. Bad software design, IMHO.
