Fab9Tuning Plug & Play Coil-On-Plug Conversion Kit

(23 reviews) Write a Review

Expected build time is 3 days.

FAB9 has yet another great solution to your Miata performance problems. The factory ignition system is not awful, it just wasn’t intended for the performance that we have in mind for our little roadsters. This ignition system is one of the most complete and easy to install packages available. On top of that, it might be one of the most affordable routes to take!

Mazda Miata MX-5 1990-2005 Mazda Miata 1.8 and 1.6 engine 5 and 6 speed transmissions. This setup will convert your NA coil pack and NB wasted spark setups to an individual Coil On Plug.

NOTICE: EARLY LINK ECU COMPATIBILITY ISSUES - Customers have reported module failure while using the LINK ECU.

NOTICE: HYDRA ECU is not compatible.

NOTICE: If you have a swapped engine, order the kit that matches the vehicle harness, not the engine!

Due to the number of variables, we cannot guarantee the compatibility of all aftermarket engine management systems. We also will not accept returns on Hardwire kits due to the nature of installation possibilities.

As it turns out bench testing has been done to show that the Toyota Coils commonly found in many conversion kits aren't much stronger than the stock NB Miata Wasted-Spark setup. The dwell settings for the Toyota COP are not a very good match for the Miata factory ECU, they will not tolerate the factory dwell settings for long. With our external ignition module you don't have to worry about dwell tolerances, even on the 99-00 cars.

Unlike the Toyota Coils these have the coil windings down the shaft and an external ignitor so they aren't top heavy, they simply need the correct diameter holes to press into, and a spark plug to attach to. The weather seal at the top steps up in size allowing a firm fit for both the NA/NB/NB2 (MSM) valve covers, making them a perfect match.

This kit out of the box is not designed to support huge power numbers. It will support +/- 18PSI when paired with the included 4-Channel Coil Driver. If your setup requires more you can simply upgrade to the AEM Twin-Fire Ignition Module PN:30-2821. Our Pencil Coils paired with the AEM Twin-Fire result in a very serious 1000HP capable spark setup.

- 4 x Pencil Coils, connectors, connector pins, pin lock and weather seals
- 1 x 4 channel ignition coil driver, connectors, connector pins, pin lock and weather seals

- 4 x DENSO spark plugs (compatible with pencil coils)

- 1 x Fabricated harness
- 1 x Install Manual

Easy to follow conversion instructions are included. Support - We're here to help!

NOTICE: At this point these kits are in such high demand they are build to order. There is an estimated 3-4 day build period depending on the current demand. There will be a 15% restocking fee on any order returned (must be un-used and in perfect condition).

    Took less than 10 minutes to install, amazing results!!! Smoother rev range, improved spark. Well worth the money. Can't beat the price for brand new products, and not cheap ones. Recommend to anyone with performance in mind.

    The FAB9 team has it covered. Ordered on a Friday. Had the system by the next Friday. Ordered the hard wired for 90-93. I had to call 1 time to make sure it is that easy to in stall. If you don't have a TACH adapter. Order the AUTO METER at the same time. Done in less than 2hrs. It took that long because I had to have a beer break. Helps de-clutter the engine bay and really tidy things up.

    Best with some adjustments

    Posted by John Hinton Jr. on Sep 4th 2017

    Hello, I love the COP kit you guys have made, I was able to install it the night I started and was easily able to go into to boost. There are some things I think would ensure your kit to be the first choice for a swap. First and most important, I think your instructions need to be a bit more detailed. I had to go onto to forums and google and find either different instructions to confirm the cutting and soldering and placement; or I would have to find old photos you have previously used in your instructions. Talking specifically about re-setting up the tachometer, with or without a PNP ECU would be very useful in both sets of instructions. Most important about the instructions was the comment a friend and I both came up with while doing the install; "the directions seem simple for the guy who does this day in and day out, and hard for the guy who just bought the kit." Next and Secondary, a harness that matches the igniter harness so to minimize the confusion in cutting and soldering would be useful to the swap and probably not too expensive to integrate into your design.These simple suggestions can either make the install less stressful on the customer and/or greatly increase your company's popularity with this kit. Thank you for listening and I hope to get more parts from you soon.

    this kit is awesome

    Posted by kyle Scerbo on Apr 24th 2017

    At first I bought for preventative maintenance but came to find out it actually let out hidden beast within. Great throttle response and a little peppier. A noticeable difference in power in the best way possible. Would recommend to my grandmother. Great job fab9

    Great product, super clean look.

    Posted by Shane on Apr 18th 2017

    This kit was built in a short amount of time and installed very easily. Had some issues with my one Driver blade connector not reaching the wiring harness in the plug, must have been a factory defect. Fab9 sent me a new driver quickly, the setup works great and feels very smooth. My valve cover looks so clean an modern now. Great product and customer service.

    Worth every cent

    Posted by Robert Osborn on Feb 24th 2017

    Bought for my NB1 as preventative maintenance. My last NB1 went through coil packs like nobody's business. These installed in under an hour and the car fired up the first try. It idles smoother and it seems a lot more smooth in the powerband. I definitely recommend this COP kit. The coils are very firmly on the plugs and sealed around the holes in the valve cover, so I have no worries about these potentially coming loose. Just buy this COP kit!!

    Well made, easy install

    Posted by Art on Jun 25th 2016

    Bought this kit a few months back and finally got around to getting the car out of storage and installing it.

    Couldn't have been easier, plug and play, half hour job after you worm the old coil pack out of its tight location.

    Fired right up, idles smoothly and pulls strong thru the power band.

    No more carrying along a spare coil pack for my 00/NB

    I highly recommend this conversion

    Clean Install, better spark

    Posted by Ege on May 8th 2016

    The most difficult part of the installation is getting the old coil system out. Once you have that done the installation of the Fab9 system is straight forward and simple. I'm getting a better spark across the power band and much less detonation at lower RPM's in higher gears. It feels like it has a stronger pull from a lower RPM range right up to redline.
