Mishimoto Intercooler Review & Buyers Guide

If you’ve searched the internet looking for a Mishimoto Intercooler Review, you’ve found the right place! We take a look at their most popular fmic units. While being one of the most popular brands on the market, trying to find reviews and horsepower ratings for these intercoolers isn’t easy. Actually, it’s almost impossible. So we’ve put together this quick guide for you.

Who Is Mishimoto?

Mishimoto is a performance parts manufacturer that offers many different lines of products. From daily drivers to full-on drag cars, they make something for just about everyone. Tons of research and development go into their parts, resulting in the best bang for the buck products available. Take a trip to your local car show or drag strip and you’ll see Mishimoto parts being used by gearheads all over. Once a go-to for the import crowd, they’ve since branched out. Now covering just about every area of motorsports, there is.

Why Review Their Intercoolers?

We’ve installed many of these intercoolers over the years. We’ve also tuned dozens of cars using their FMICs. After noticing the lack of Mishimoto intercooler reviews online, we wanted to share our experience with their products. In our opinion, they are as good as any other brand on the market.

The Z-Line, J-Line, and R-Line are the most popular of their FMIC’s. Therefore, that’s what we will be covering. If you’re looking for info on another model, please shoot us an email.

Mishimoto Z Line Intercooler

First up is the entry-level Mishimoto Z-Line intercooler series. The engineering department managed to squeeze lot’s of cooling power into an efficient sized core. With a small footprint and six threaded mounting bungs, installation is about as easy as you can get. Using an efficient bar and plate core with sizeable internal volume lets this little guy cool more air than you would think. They are rated to withstand up to 22psi; the Z line is for smaller builds. You’re not going to run 9’s or be a dyno queen with this FMIC. But you will crack a big smile when the boost kicks in.

This Z-Line offers the following features:

  • All-aluminum construction with bar-and-plate core
  • TIG-welded end tanks for increased strength and durability
  • 6 threaded mounting points for universal fitment
  • Rated to 22 PSI
  • Available in Sleek Silver, Stealth Black, or Bold Gold
  • Mishimoto Lifetime Warranty

This Mishimoto Z-Line intercooler is rated up to 325 HP


J-Line Intercoolers

Next up is the Mishimoto J-Line intercoolers. The next step in performance and are used in many of their popular intercooler kits. We’ve installed this core on numerous cars and have always been impressed with the quality and performance. Comparing it to other FMIC’s at similar prices, you can see why it’s so popular.

Using high tech Fluid Dynamic software, they designed a compact intercooler that maximizes airflow and minimizes turbulence. The J Line uses high-density internal fins to increase cooling capacity by optimizing the inner surface area. The intercooler was put through rigorous testing on their in house Dynojet dyno. Advanced temperature and boost testing were also done. In English, this thing flows a ton, cools a ton, and results in maximum fun!

Painted vs unpainted cores were also tested to see if there was any performance loss due to the paint. It turns out it made zero difference. Who woulda thought?

This FMIC offers the following features:

  • Durable bar-and-plate core provides superior heat transfer while effectively reducing AITs
  • Robust, one-piece cast aluminum end tanks withstand high boost pressures
  • Large 3.75″ thick core and 2.5″ inlet/outlet provides optimal flow and volume for high horsepower vehicles
  • constructed with 6061 aluminum
  • Available in Sleek Silver, Stealth Black, or Bold Gold
  • Mishimoto Lifetime Warranty

This Mishimoto J intercooler is rated up to 500 Horsepower


R-Line Intercoolers

Last and far from least is the Mishimoto R-Line intercooler, look at this big boy! It can handle a lot of HP and a ton of boost. However, this requires using a much bigger core. This massive intercooler is 31″ long, 12″ tall and 4″ thick! Featuring 100% aluminum construction with cast end tanks tig welded to its bar and plate core. It also comes with 4 universal threaded mounting points, sweet. Available in silver or powder-coated stealth black. The Mishimoto logo is located on one side (so you can hide it if you prefer). This FMIC is big, it’s bad, and it crushes! It handles anything most cars on the street can throw at it, with room to spare. It’s by far our favorite Mishimoto intercooler to review and test on the road.

We’ve installed quite a few of these, and they rock! By far, my favorite intercooler for fun street car builds. Compare the performance to any of the “big name shop” FMIC’s, and you’ll quickly see what a bargain this intercooler is. Equal or better performance at 50% the price. Let the other guy overpay for another brand, and you save the extra cash for more parts!

FEATURES:

  • Durable bar-and-plate core provides superior heat transfer while effectively reducing AITs
  • Robust, one-piece cast aluminum end tanks withstand high boost pressures
  • Massive 4″ thick core and 3″ inlet/outlet provides optimal flow and volume for high horsepower vehicles
  • Mishimoto Lifetime Warranty

Gold Mishimoto Intercooler Option

The Mishimoto Gold Intercooler has become one of their most popular color options. It adds a very distinct look that pops when peeking out from behind your front bumper. There is no performance difference between the Gold Series and the standard finishes. It’s merely a visual upgrade over the standard versions.

The gold finish is available in both their universal and direct fit intercooler kits.


Mishimoto Intercooler Kits

Mishimoto also offers a line of direct-fit intercooler kits for many platforms. The core used in the kits varies depending on the vehicle.

The kits contain everything needed for a worry-free installation. Including an application-specific crash bar that both supports the intercooler and mounts to existing points on the vehicle. No cutting or drilling is required to install the crash bar and intercooler. The kits include all necessary mounting brackets, including a relocation bracket for the coolant overflow bottle. All mounting brackets come with applicable hardware, zip ties, and thermal wrap. The FMIC kits also include every coupler and clamp you need for a clean installation.

We’ve installed many of these kits and have always been impressed with the fit and finish. For most people looking to add a fmic we recommend finding a complete kit whenever possible. It makes life much easier.

Mishimoto’s research & development team put a ton of time and effort into developing their fmic kits. Every step from concept to completion is engineered for both performance and quality. They have excellent videos on their YouTube channel that break down the process they use when designing a new part. If you want to learn more, I highly recommend checking it out.


Warranty

One of the best features of any Mishimoto product is their fantastic warranty. All of their products carry a ‘no questions asked’ limited lifetime warranty policy. Regardless of the defect in the product, Mishimoto will replace the original part. They only ask that you submit warranty claims with the original sales receipt from the authorized dealer where you purchased your intercooler.

Accident Protection 

Mishimoto also offers no questions asked Accident Protection on their products. They will provide a warranty for all claims, including vehicles involved in accidents. Warranty claims must include pictures of the accident along with an official police report of the accident. The claim must be submitted within three months of when the accident occurs.

Final Thoughts

In closing, we love these intercoolers. They perform as well as some of the more prominent names on the market and cost considerably less. The fitment is top-notch, and the warranty is outstanding. Plus, you get the accident protection, which nobody else offers.
