Subject
Works perfectly as claimed, increased oil pressure from 25 to 35 psi.

Did this item work well with your project? What vehicle type are you using this for?
Easy to fit, obviously won't fix the oil pressure if your main bearings are worn (common issue on the RV8) but on a good engine it works exactly as claimed, +10 psi roughly compared to the standard spring.
