Cooling fans weren’t working, so replaced the relays in the front left with this and it worked perfectly after.

Great replacement for OEM /manufacturer relay. Good price works perfectly. I would buy again 10 out of 10.

Was getting intermittent trouble with my 92 Miata engine turning over but not starting.Traced it to the fuel pump randomly not engaging.Replaced fuel pump relay with this item and all is well.Have read where this one may not be as robust as more expensive ones. I had not considered that.Also have read where people buy an extra and keep in car in case this one fails.May consider that as the cost of two was still less than others I could find.Overall happy with purchase.

Took a chance, it states that it won't fit a 90 Miata but it does fit and work as it should. Great alternative to the 60$+ relays out there.

This Standard Motor Products RY-667 Main Relay was just what I needed to complete my new invention! The Weasel-Wacker 3200. Thanks for having the right part at the right time!

The original Japanese version of this relay no longer seems to be made anymore for our Miatas. After spending close to $1000 at a dealership to fix my Miata, I ordered one of these and it took less than a minute to replace. Instantly my 2001 Miata is running as new. I also now keep a spare in my glovebox as well as spare fuses, a camshaft, and a crankshaft position sensor. Don't leave home without them!Update on 7/8/23: Almost a year later and still working great!
