Autotech is a premier manufacturer of fuel pump upgrades for the DISI MZR I4 engine because their kit offers the highest quality, solid engineering, and great value. Autotech's HPFP Kit can achieve flow rates ~50% higher than the original pump, essentially removing pump limitations from the equation, even on high-end turbo upgrades. Autotech's HPFP kit continues to be the benchmark that imitators strive to reach. However, Autotech's HPFP Kit is not easily duplicated. There are many reasons why Autotech's Kit is well made. Here are a few: *Each piston (9.8mm) and cylinder in Autotech HPFP kit undergo high-precision grinding processes many times during their manufacture, ensuring that the most precise tolerances are maintained through the final step. Not the cheapest way to make them, but the best way. *Each piston and cylinder are match-ground and serialized to ensure absolute precision and the utmost longevity. *Autotech was the first to incorporate plasma DLC coating on HPFP components to reduce friction losses and increase performance. Others have tried to follow by adding a coating to their parts. However, the DLC process alone is not enough - it is not a cure for substandard precision - the parts must be engineered specifically for the process to take full advantage: Autotech's are. The success we have in the field can attest to that. *High Volume Fuel Pump Upgrade is compatible with COBB OTS Maps. Tuners trust Autotech's HPFP in their conversions and upgrades because it works, and works well.

MAZDASPEED Fuel Pump Internals is rated 5.0 out of 5 by 53.
Rated 5 out of 5 by from finest HPFP out there ! Was so eager to installed my Cobb Downpipe however I didn't know which HPFP to get, and finally came to a conclusion and got Autotech internals. Great product ! installation for the first time was pretty long (took about 3hrs), but i took my time and made sure i was doing everything properly. after installation, did a quick log with my Cobb AP to make sure everything was properly done. great product ! definitely worth the money ! PS: installed another autotech to one of my buddy's MS3 and it was 45min installation time. go get this beast guys !

Rated 5 out of 5 by from Does exactly what it says Bought the hpfp to accommodate my new Cobb downpipe and was not disappointed. Never drop fuel pressure at WOT. Install took me 3.5 hours and I by no means think I'm mechanically gifted. Cleanliness is key during the installation and it's best to just take your time. There's many videos you can watch and forums with pictures if you run into trouble. NOTE: Be sure to prime the car afterwards by turning the key to on but not starting it so you run the pump a couple times.

Rated 5 out of 5 by from Good product I bought this at the same time as my downpipe, I have not installed the downpipe, but i finished installing this the other day. I bought this after my intake inlet and accessport because I did not experience a drop in pressure, but based on all the reading this is necessary. I followed the COBB video tutorial to a T and install was not bad, just make sure everything is clean, and you have the proper tools. Took me about 4 hours, and everything is running great, no noise, and no smell. This product does exactly what it says I would recommend it for anyone who needs something reliable.

Rated 5 out of 5 by from Great Product I bought this for my boyfriend and he loves it. It really improved his cars performance. It was hard to install, but worth it.

Rated 5 out of 5 by from Very well machined There are so many videos on YouTube that make this install super easy! I cannot notice a difference in power but that is because we installed the entire stage 2 kit. My only issue is the cost...I understand the machining, and I understand the need for increased volume and pressure...but it is pricey

Rated 5 out of 5 by from 1,800 psi at WOT! Time for down pipe! These internals are so highly engineered and precisely machined. The install was tedious and time consuming but it should be if your doing it correctly. Don't take this install lightly. This is like doing surgery on your car and you should treat it that way. If you drop, scratch, forget to clean, forget to lube or not torque something to spec.. it will go badly. If you respect the part and follow Cobb's instructions word for word you will be successful.

Rated 5 out of 5 by from Big Difference I bought this about a month ago. Install was done along with the TIH. It did take me a while but I took my sweet time. Before fuel pump internals, 1st and 2nd gear would have a huge pressure/ power drop around 4900 to redline. Especially when it started getting a little colder down here in AZ. Now, it's a thing of the past. My gen 2 speed3 now is strong through the entire rpm range. Definitely a must in my opinion.
