Glowplug Question

[Ericke1]

I have 4 buggies with the following engines:

Inferno MP-6 International with .21 O.S. Max .21RZ-V99B
Ofna Violator with Force .26
Thunder Tiger Mirage VSPEC with .21 TT Pro VSPEC Engine
EB4 S-3 with .21 Kanai Evo II Engine

We all know how often we need to change glow plugs. I saw that rc-mushroom.rcmart sells 5+ more packs for around 20 or so bucks, and Im interested in buying turbo plugs for my engines or Sirio S6 Cold in a 18 pack for about 60 bucks.

Please see the links below and let me know which glow plugs you believe are a good value and optimal for my engines, I have a friend coming in and will ask him to buy some packs for me. Thanks:
