cone filter on 2.9l

[91cx]

I dont know much about engines so and i added a cone filter to my 90 ranger xlt, there is a wire attached to the air filter box, I was wonder what i should do with it, maybe drill a hole in the air intake piping and put it in?

Are you sure that isn't a vacuum line? What engine is it?

You want no leaks in the intake tubing, I wouldn't recommend drilling a hole into it. The only place you should be getting fresh air from is through the cone filter.

I am really not fimilar with the 2.3L from that year, is it the 2.9L? If it is, I am thinking there should be 2 lines that need plugged from the vacuum tap on the upper intake manifold. And the other should go to the MAP sensor. If it's any other engine, this won't apply. Basicially, you need to get fimilar with the vacuum mapping to know which systems you've eliminated. Once you determined what's not working anymore, you need to plug off the approperiate vacuum lines.

I went with a MAF conversion and ended up eliminating an entire tap of vacuums on my 2.9L. Replaced it with a NPT brass plug and called it done. Much cleaner and easier to get the valve covers off if needed.

DO NOT CUT the transmission vacuum line.

On my 88' there were 2 lines that needed plugged from the vacuum tap on the passenger side intake manifold. You can probably just get away with plugging that one depending on how much of the old intake system you have removed. When everything is going again, plug the line with a self tapping screw. If it's idleing high, you will need to go through the vacuum routing and see where you have a leak.
