works great

Nice and bright compared to stock bulb.

So far I’m liking it, but need more miles to see if it’s meeting my expectations.
My main need is an assist in rev matching at lower speed, in lower gears.
I need to play with it a bit more.
I drive a ‘23 Miata.

Horrors! After years of passing the Arizona emission test, my Miata failed this year (2025)! Basically the CO reading that was over the limit. Reading the details provided for the O2 sensor offered by FM for my NA Miata, I found that the O2 sensors can degrade causing an overly rich fuel flow, and mine was now over 30 years old, so I ordered it, fitted it and went back to the emissions test station and passed easily. So thanks Flyin' Miata, as usual finding the right part, ordering it and receiving it safely packaged was easy!

Installation was easy and everything fit perfectly!

Works exactly as advertised ! Really pleased with this.

Great tool to use and makes the oil changes less messy. Routing the hose down to the bottom is a bit of a challenge and the space in front of the lower control arm is where I routed mine. I recommend doing this after the oil has been drained and plug replaced.

Installation is well documented both in video and written form. The most challenging parts of the installation are due to a lack of space. FM did a great job providing tips for access. The key is patience, and trying different tools and angles of attack. Mirrors, extended magnets, and various socket extensions are highly recommended. The installation took me and the occasional helper four days doing one step at a time and a couple trips to the local auto parts store (no lift). With a lift, a dedicated helper, and a lower amount of distractions, this install could be done in two long days (not including the welded cat). Initial operation was issue free. All we had to do is dial in the boost setting (also documented). Okay on to the drive...

Car starts and idles like stock, except it seems slightly quieter. I have a very mild exhaust upgrade and you almost can't tell. If it wasn't for the Banks gauge (which I highly recommended for monitoring boost and temperatures), it would seem totally stock. I am not sure anyone would notice the car is modified when driving it around a low speed parking lot. It's totally OEM, and I cannot stress how impressive that is on car that has had a power increase or 50% or more. Once you pull out on a main road, a totally different personality emerges. As you pull pass 3K RPM towards 4K, the power surges wonderfully and predictably. Turbo noises become very present inside the cabin and become addicting, but never annoying, easily drowned out by music at moderate volume. Think of having the torque of a lightly modified turbo hot hatch, but in a RWD car 500+lbs lighter. Highway passing is now a breeze in 5th and 6th gear. There is plenty of power to throttle over-steer around corners in 2nd and 3rd. The NC chassis is awoken by the power increase and in combination with my suspension set up, is one of the best drivers cars I have driven at any price including many Porsches, BMWs, and recent muscle cars. If something happened to this car and I had to replace it, I'd be shopping for NCs to turbocharge with this kit the very next day. That is the best compliment I can give the Mazdaspeed NC Miata that could have been and Flyin Miata made possible.

Super affordable, quality piece. A must buy if you’re rebuilding your latches and have worn down locking caps.

Well made, long with knurled ends, easy to use. Really gives the car an awesome look, which equates to more horsepower as we all know.

Do it!

The hardest part is grinding down the negative post per the exceptionally clear instructions and YouTube installation video. Even that is straight forward. (I picked up a ~ $35 portable belt sander at Harbor Freight. Did just what I need and now I have a new tool that can sharpen my lawnmower blade. lol.) The second hardest part if lifting the old battery, because it's a small space, but also more than big enough for the smaller new LiFePO4 battery. Couldn't be happier with this product: battery, mounting kit, instructions. You know you'll have to replace your battery. While this one is more expensive than a lead-acid, it will also last twice as long. So basically same price and less maintenance, plus (and this is the biggie) better handling because of the weight savings. Would buy it again.

Good quality and best price. Easy enough to replace it but if any questions come up you can always ask FM for instructions. Their customer service and support is the best. Will purchase from them again and again when need it.

Magnificent. Works great.

perfect fit

These look and function awesomely, and they were super easy to install. Well worth it!
