For $120 these are the closest to OEM quality you can get for the Mazda 6 (especially if you keep the stock projectors). If you still have halogens in your Mazda 6 these will be a HUGE upgrade. Honestly at first I wanted LEDs just for the elevated front end, but I never realized how dim the stock halogens were until these were installed!

Morimoto 2Stroke 2.0 H11 LEDs: https://amzn.to/2NlZWKE

Pros:
-made with high quality materials
-very reputable and established brand
-huge improvement in light output
-plug and play
-no warm up period like HIDs
-Morimoto has exceptional customer service

Cons:
-the cooling fan is pretty noisy
-wiring is on the longer side so you have to secure the excess to the fusebox cover or hardline
-for those of you with upgraded headlights/OEM LEDs may not see an improvement or they could be worse

Bottom Line:
Mazda 6 that still have their stock halogens would greatly benefit from this switch. These are the closest you’ll get to OEM quality for the price point (if you find an alternative let me know because I don’t know of any). The Morimoto 2Stroke 2.0 LEDs have been reliable and made me enjoy my 6 more than I already did.
