Engineered Power That Goes Further. Power Glide 8 GLV‑1 0W‑8 Performance Motor Oil

From the factory, the plastic inlets are limited and allow very little volume to pass as they neck down dramatically to the turbochargers themselves. This reduction stifles flow and increases the pressure ratio pre-turbine causing the turbochargers to work harder than necessary. This is a problem Dinan engineers took great care in rectifying through exhaustive prototyping and testing to ensure maximum future power potential while also having compatibility with numerous potential configurations. The benefit of their hard work are Dinan Turbo Inlets that are constructed of gloss UV coated 2x2 carbon fiber and are designed to mate seamlessly with whatever level of modification to the intake system you anticipate (paired with either stock air boxes or the full Dinan Cold Air Intake System). Where the carbon fiber ends an aluminum adapter to connect to the stock turbocharger begins. Using the same factory locking system, installation in this area is straightforward and earmarked by a "click" when secure. The simplicity making this quite possibly the quickest and least aggravating installs on the platform you will encounter. The pipe itself has been created to offer the largest possible cross-sectional area all the way from the intake filter to the turbo, a staggering 200% increase in volume over stock. This is the key to maximum performance gains from the system and the reason for the organic and unorthodox shape of the Dinan inlet system. While the effects of the additional volume are pronounced on a vehicle equipped with the factory airboxes and results in average gains of +11 WHP / +13 WTQ from 2000 RPM to redline, the overall efficiency of the entire intake system is maximized when paired with the Dinan Cold Air Intake that is also delivering an increased volume of cooler air earlier in the intake tract.

KLM Race: About Us

ABOUT KLM RACE

DYNO TESTED.
RACE PROVEN.

THE BEGINNING

In 2015, KLM Race started in a small industrial storage unit with no heat, no AC, and no shortcuts.

It was just long hours, extreme conditions, and a commitment to figure things out the hard way. Working through 100+ degree summers and freezing winters, building parts by hand, and pushing forward without outside funding or a safety net, just a vision, and the willingness to bet everything on getting it right.

FROM HONDA TO BMW

What began with fabricating Honda manifolds and parts, quickly evolved into something bigger. Early investment in a CNC machine and dyno allowed for real development, months of testing, refining, and dialing things in until the results spoke for themselves.

WHERE WE ARE TODAY

Today, KLM Race operates as a full-scale fabrication and machine shop specializing in high-performance BMW platforms. From complete engine builds to turbo kits and precision-machined components, everything we produce is built with purpose and backed by real race proven results.

BUILT IN-HOUSE

In an industry where many companies rely on reselling and drop-shipping, KLM Race takes a different approach.

We design, machine, and build as much as possible in-house. When a component can't be produced internally, it is carefully sourced, rigorously tested, and held to the same standards as the parts we manufacture ourselves. Nothing is added to our lineup unless we trust it completely.

THE PEOPLE BEHIND THE WORK

But what truly sets KLM apart is the people behind the work.

The same individuals machining and assembling these engines are the ones who care about how they perform. There's no disconnect between production and outcome, every part is built by people who take pride in doing it right, not just getting it done.

We don't cut corners. We don't chase shortcuts. We prioritize quality, performance, and results, every single time.

We've grown a lot since those early days, but the mindset hasn't changed.

TESTED UNDER PRESSURE. PROVEN UNDER POWER.

WHO WE ARE

THE TEAM

KLM Race is more than a shop, it's a team of people who take pride in what they build.

From machinists and engine builders to the guys who step in wherever needed, everyone here plays a role in the final product. There's no disconnect between the work and the outcome. The same people behind the machines are the ones who care about how everything performs.

Everyone has their place. Everyone contributes. And that shared standard is what keeps our quality consistent and our work reliable.

This isn't just what we do, it's who we are.

WHERE WE BUILD

THE FACILITY

KLM Race operates out of two dedicated buildings, each serving a critical role in how we work.

BUILDING ONE

Machine Shop

Our machine shop is where parts are designed, machined, and brought to life. With CNC equipment and a focus on precision, this is where raw material becomes the foundation of everything we build.

BUILDING TWO

Engine Assembly & Dyno

Our second building is dedicated to engine assembly, vehicle work, and performance testing. Equipped with lifts and an in-house dyno, this is where engines are not only built, but proven.

By separating machining, assembly, and testing, we're able to stay focused, efficient, and consistent at every stage of the process.

From raw material to dyno-proven performance, everything is handled in-house, giving us full control over quality, fitment, and results.

Feedback from Our Customers

Reliable Even Under Pressure

I do a lot of highway driving and my engine runs cooler and quieter with this oil. No complaints, just great results.

Mike Johnson,

Long-Haul Driver

My Engine Feels Brand New

I switched to Power Glide 8 after reading about low-viscosity oils. It made a big difference—runs quieter, smoother, and cooler.

Kevin Howard,

Mechanic

Perfect for City Driving

Stop-and-go traffic used to make my engine heat up fast. Since switching to this oil, it stays stable and efficient. Big win.
