Anyone using this? Do we get the 'Twist' or 'Push'?

 

You need a screw on, we've got them in stock, $15 plus ship, with the chrome top.

You should get a chip as well, to correct for the unmetered air that will be ingested, or you can get a check engine light.

 

Thanks for the info Sal!!

 

Autozone has a nice chrome one for $11. Its a push in style, 1-1/4", but it is a snug fit and twists in. Only one I would mail order would be a billet screw in type, but no rush on that as the chrome one looks good and will work for a long while.

 

I had a 'push-in' type and it would be knocked loose with just the lightest of a touch. I changed it to a PSP 'twist-in' because the threads on the cap match the threads in the filler tube. It won't be knocked loose inadvertantly.
