Can you get wire covers for H23a's? I am hoping that is not a flamable question, but I have just never seen one on a H23.
Or can you just use the H22's cover?

 

I've never seen one.

 

I am assuming that you are referring to the cover that goes over the plug wires on the valve cover?
if so I am about 99% sure that there is none. The wires sit too high. I looked myself back when I first got the car. Maybe someone makes a ghetto one. you can check e-bay

 

Its a shame they didn't make one then... It makes the engine bay look a lot neater, and especially since they sold more h23's than 22's. I wonder if a h22 wire cover coul dbe used on a h23, if there were some spacers and longer threaded bolts to compensate for the higher sitting wires?

 

Just get a H22 and loose the weak H23, and you will have a plug wire cover.

 

Oh, now why didn't I think of that?!?!
maybe I can just try duct tape...
