[NSRCA-discussion] K&B 4C Plugs

[Ron Van Putte]

I have been wondering about how contributors to the NSRCA List feel  
about the performance characteristics of K&B 4C plugs (K&B 4444).   
Apparently the K&B 4C plugs have been discontinued, but some  
distributors still have good stocks of them.  I wondered about their  
performance because they appear very similar to OS F plugs, but cost  
much less.  In my limited experience with them, they appear to give  
very much the same performance as the OS F plugs.  I've seen used  
them locally in OS 1.40RX engines with very good success.

Does anyone have any comments about them?
