On my stock FL5, I noticed a big jump in sound and an increase in performance. Now, every pull with the PRL HVI feels like the first pull on a cold day with the stock intake. Despite everything heat soaking, you still get pushed into your seat hard.

Only downside is my poor tires are suffering from my foot suddenly getting way heavier.

Fitted for the FL5 and fits perfectly. Love that the cap has a nice pearl in the coating when the sun hits it. Definitely a great piece for HKS lovers.

Arrived on time.

Just got it installed after Chinese New Year, completely changed the way the brakes felt and the way the car stopped and handled. Believe me when I say that this is the single more cost effective way to upgrade your FL5 brake system.

Brake pedal was way more solid with less to no initial play and that is with my brake pads worn out after about 30,000 km.

Great communication! Fast shipping. Will order more parts from Unity Performance

Exactly what i was looking for. Great communication. Quick shipping. Will buy from unity performance again !

After the install, I love it. Install was a little bit more difficult than anticipated, especially for the locking housing that turns the trick I found to get that in was to not install the map sensor. Using the hole to get a better grip to help lock it into place then complete the rest of the install as instructed. Aside from the install was pretty simple. Performance wise operates great the sounds are amazing one on throttle intake temperatures drop quite significantly. Although when idle intake temperatures do rise as heat soaks example today showed it was 18° outside when on idle it showed temperature was 49° but as soon as back on throttle intake temperatures dropped about 23° overall I’m happy with the purchase definitely makes driving a bit more fun would highly recommend.

The product is great. I had the PRL regular intercooler and just by carrying it I could tell the weight difference. Haven’t gotten tuned yet. Humza is the goat. Great customer service.

Glad I went with the 25mm. Feels great and no issues with install.

Very happy with the fitment and finish

Suits the engine bay way better than the cheap factory dipstick

My type S feels super sharp after installing this. The amount of adjustability is awesome and the form factor is great. Installation isn’t very difficult for a complete novice either. 10/10

These wheels are such an awesome intersection of light weight, quality construction, gorgeous design, and value that I am not sure why you would buy anything else. My 18x10.5 weighs 18.4 lbs and they look killer - in person the concavity of the wheel face and the machining are gorgeous - and I really bought them based on price to weight ratio. The latter is unsurpassed. $270 for a well built good looking wheel that weighs this little is the best value available at present. Buy a set. At these prices, buy two!

I’ll start with the Acuity shifter itself already feels super good, this is sort of the cherry on top where that little bit of extra reach just feels so satisfying, while also being lighter than the original stem. It also looks super cool, love it.

These are by far one of the biggest improvements I’ve done to my FK8 over the years and I’m very particular when it comes to brake feel and modulation, but do these ever make a good bit of a difference. Install is somewhat annoying since the tolerances are very very small, but it’s all made worth it once you get on the brakes and feel the difference.

Easily a must have.
