I was very skeptical of the other reviews saying it woke up their stock engine but its true (at least for me). Wasn't anything extraordinary, but my motor did feel a little more torquey and a tad more responsive, I honestly was surprised. Install was pretty easy, and it worked as soon as I cranked, for NB1 motors, the coil pack connecting port is at the front of the motor, not at the back and due to the length so you cannot secure the coil pack to the firewall. I luckily had a strut tower brace that I could JB weld a bracket for the pack onto, but others watch out. No reliability issues so far, but the securing rubber rings around the coils that prevent movement don't work too well and mine move around a little bit up and down, but I've never lost spark so far. I'd suggest FAB9 address this issue with a securing bracket.

Currently installed on my 99 turbo. Runs on megasquirt fine. Quick and easy install, and there are step by step videos for people who may not be mechanically inclined. Install difficulty 2/10, very easy.

The kit worked great, the instructions confused us a little bit during the install, but I think that was more we were not installing on a Miata, rather a Escort GT. Besides that the kit works great and will be making its debut at Watkins Glenn next weekend.

Super easy install cleaned up the top of the motor very nicely . Call response seems to be improved as well .

Plug and Play EASY, good build quality. Instructions were on point. Car idle issue SOLVED!

I am a big fan of this kit. It fit my turbo 99 with no issues and handles 14 psi easily. The car also runs and idles smoother. My only complaint is that the spark plugs which came with this kit did not fit the coil packs. I sent a picture to customer service on FB and they confirmed that they were not the correct plugs. I wanted to get the car on the road so I visited an Advance Auto 30 minutes away and got a set of the correct plugs since that was the nearest store which carried them. Customer Support on FB said they would fix the issue the next day and I told them I would be satisfied if they just sent me a spare set of the correct plugs. I never received a response. I attempted to contact Fab9 several more times over the course of a month and the messages showed they were read but I never received any sort of response. So looking back a month later, the kit is wonderful however I customer service is not the best and I do feel that it was reasonable to ask for a set of spare plugs seeing as how I had paid for the correct plugs included in the overall cost but did not receive a set which could be used.

97 Miata Simple install Engine runs great. Removed old coil. Nice space now. Thanks guys.

This kit is simply awesome. Roadster turns over quicker. Running the iridium plugs gives more responsiveness with the gas pedal. Do a rough install to make sure module is firing ok. After confirmation it’s much easier to mount by removing the factory coil on a Miata and mount with zip ties to break lines and available hoses to keep from tapping firewall while driving. It feels like it woke the car up. Works great with entirely new exhaust system w header.

I have to say that I didn't think it would be a difference in performance. But I have to honestly say that it is well worth the money. One of the best investment for a miata 5 star easily
