Keep it or lose it? I know it is good to have it if you go "agricultural". Is it legal to leave it off and what advantages are there, other than the obvious?

No question, you want to leave it in. Too much drag without.

I originally left mine off thinking it would be easier to work on the car and not knowing any better but a little cordless drill with a 10mm bit does wonders.

Doesn't really get in the way of much. I change engines without removing it.

It ABSOLUTELY increases drag and DECREASES cooling if you leave it off. No question - you should definitely keep it. Don't believe that little bit o' plastic can make a difference? Try some back to back testing.

Cheers,

I did a direct back-to-back test with it on and off and found it affects both your top speed and the cooling to the radiator. Leave it on. Anything you can do to legally smooth airflow under the car is a big win.

Thanks for the help guys, it all make sense. I had no idea it would effect cooling and drag so much.

Anyone have a p/n for that plastic engine tray? Searched Mazda Motorsports but can't find that thing anywhere.

The bolts are the same as 100 other bolts you took off the car for something you long forgot and are sitting in a tin somewhere. I never run out of those.

I looked at one and the shipping was more than the part, so I got a used one locally.

I think the shipping was like $10 and arrived in a week.
