[urq] FW: plugz

[Buchholz, Steven]

... regurgitating a post from my archives on plugs for the urq ... 

Before I went to the F5DPOR I used the WR5DS plugs religiously ... they
seemed to work well and last a long time.  

For those who do not know, the "F" prefix means that it has the clip on
plug wire fitting like 'murkin cars have ... if you have the factory
wires you need to remove the adapter.  I got wires with the proper
clips, but if you want to use the factory wires you can go with the "W"
prefix ... W5DPO ...
