The Kat's Heaters Ether Start Fluid Injection System # KH33180 is confirmed to fit your 2008 Toyota 4Runner SR5 4.0L V6 Engine. Simply pull a knob that installs in your cab to inject ether fuel (not included) into your intake manifold and get a fast, reliable startup in cold weather. |

This is a great way to ensure starting, but the other components will still need a little time to warm up. There is a pull knob option # KH33180, a push button option # KH33112, and an ignition switch option # KH33220 for your vehicle. |

So I would use wheel locks and a coupler lock such as # FA86-0015-318 as an example (there are many types of coupler locks) similar to how a door might have a lock at the knob and a dead bolt lock. Now, if only the tow vehicle was that secure. |
