Volant doesn't make an intake yet for the 6.4 yet do they? I don't run a washer bottle on my jeep, don't ever use the windshield washer so I didn't see the point and saved the money. You will have a low washer fluid light pop up on the dash though so you will need to jump the the 2 prongs on the washer fluid level sensor together with a wire to get the light to shut off. I'd get the intake before the exhaust

I found a few on eBay that says they will fit the 6.4L. Maybe not. I will confirm and get back to you.

Don't believe it if it says it fits a 5.7 it won't work. Someone either on this site or the other bought it because it said it fits but it doesn't because the 6.4 has that curved neck coming off the intake maniffold and the 5.7 doeant
