Query: Works well, but a few thoughts...

Installed these a while ago and I must say they are far superior to the units they replaced (OEM 1988 Celica Alltrac.) The spray pattern and adjustment is very nice and works well. When installing these, be sure to take precautions against over tightening the plastic retaining nut as you will strip the threads on the nozzle. Aside from that I would be sure to check clearances under the hood. The plastic nuts are large in diameter and you must have room to tighten them against the top hood skin.Bottom line: These are nice and I would buy them again.
