DIY: Subaru Forester Spark Plug Wire Set Replacement

I replaced the old OEM spark plug wire set with Exact OEM fit of NGK FX54 8772 Wire Set.
Although the old wire set resistance values were still in bound of the spec, i decided to change them since they were very close to the upper limit. Here are the resistance values per cable:

Wire order:
rear of car
   3 4
   1 2
 front o car

 Wire resistance of my forester and Ref. values:
           
                Wire resistance of my Forester:     Wire resistance specs:
                 [kOhms]                                       [kOhms]

#1 cord:     12.3                                             7.40 — 17.27
#2 cord:     11.6                                             6.24 — 14.56
#3 cord:     11.8                                             6.54 — 15.25
#4 cord:     14.6                                             6.59 — 15.37

Replacement was very easy it took about 10 minutes. NGK indicates the cylinder lead ID on each cord.
Start with putting the spark plug part of cord first and then continue with following the same way with the old wire, that is it.

I bought wire set from www.ClubPlug.net of CA. They got it from NGK dist. on Thursday and sent to Toronto by the Prulator next day shipping at around 4:30 pm. It was at the hotel by 10:30 am. I should send my thanks to them, of course also to my friend Murat who brought them to me.
