OE is best. Avoid the restEdit: but it weeps when engine is hot.

Yes cap that fixed the problem with a vapor leak for the gas tank.
Great products it's original equipment. I got this as I have a check engine light that comes on and it's due to vapor leakage. I'm sure this will be the right cap for it as I got a generic gas cap on it now which is obviously leaking the fuels.
