Your Polaris RZR 4’s engine performance is almost entirely responsible for your riding experience. You can give your Polaris RZR 4 all the fancy aftermarket upgrades you want, but none of them will affect your off-road riding performance as much as your motor. The Polaris RZR is one of the most powerful UTVs on the market. As such, its engine is nothing to scoff at in its stock form. However, we don’t need to tell you that there is always room for improvement. There are many ways you can improve your Polaris RZR 4’s engine performance. While some engine performance upgrades for the Polaris RZR 4 can be done by amateurs, other engine performance upgrades require the skill and technical know-how of professionals. Regardless of your level of mechanical ability, improving your Polaris RZR 4’s engine performance is always a possibility.

One way to give your Polaris RZR 4’s engine performance a boost (literally) is to install turbo. A turbo charged Polaris RZR 4 will leave any non-turbo charged UTV in the dust. Giving your Polaris RZR 4 turbo capabilities is like pumping it full of steroids and then feeding it rocket fuel. The best way to turbo charge your Polaris RZR 4’s engine is to order a side by side turbo kit. A UTV turbo kit for the Polaris RZR 4 offers everything you need to give your engine turbo capabilities in one easy order. We always recommend the Polaris RZR 900 / XP 1000 Turbo Kit by Super ATV. This turbo kit includes a Garret turbo charger rated for 280 horsepower, a high-performance clutch kit, a handheld ECU tuner with pre-loaded turbo tunes, a wastegate, aluminum intake pipes, silicone couplings, an aluminum water to air intercooler, an aluminum radiator, and a 2.5” stainless steel header pipe. With this turbo kit, you can expect to enjoy a boost in engine performance of 35 horsepower as well as a 30 feet per pound increase in torque.

Turbo isn’t the only way to boost your Polaris RZR 4’s engine performance. Upgrading your Polaris RZR 4’s exhaust is another simple and easy way to increase your engine performance. Many UTV enthusiasts underestimate how big of an impact your exhaust has on your engine performance. Simply replacing your Polaris RZR 4’s OEM exhaust with a stainless steel slip on exhaust or turbo exhaust can be all you need to get that extra bit of horsepower, torque, and throttle response you’ve been looking for. The Polaris RZR PRO XP 2 & 4 Seater Stainless Slip-On Exhaust by Aftermarket Assassins is one of our most popular aftermarket exhaust upgrades amongst Polaris RZR 4 owners. This stainless steel exhaust is designed to fit like a glove into the factory location, allowing you to ditch your stock catalytic converter. This exhaust will give your Polaris RZR 4 much better airflow and heat reduction. It also allows you to play with the sound of your engine. On top of all the engine performance benefits that aftermarket UTV exhausts can give your Polaris RZR 4, they also look great and will add a stylish touch to your exterior.

ECU tuners are another great way to optimize the performance and efficiency of your Polaris RZR 4’s engine. ECU tuners make it easy to fine tune important aspects of your Polaris RZR 4’s engine such as its fuel to air ratio and radiator fan speed. Using an ECU tuner or Powervision tuner with some pre-loaded custom tunes is the only way to unlock your Polaris RZR 4’s true engine performance. The Polaris RZR XP 1000 Fuel Tuner For Stage 5 Exh by Trinity Racing is one of our best sellers and offers you on the fly air and fuel tuning to maximize engine performance for your Polaris RZR 4.

Investing money into your Polaris RZR 4’s engine performance isn’t an investment you’ll regret making. Without maximizing engine performance, you’ll never get to fully experience what your Polaris RZR 4 is really capable of. You may be surprised just how big of a difference an engine performance upgrade can make for your Polaris RZR. Everything Polaris RZR is the only place to shop for UTV engine performance upgrades. Maximize the performance and efficiency of your Polaris RZR 4’s engine with a side by side engine performance upgrade today!

Unleash the potential of your Polaris RZR 4 motor with the performance UTV engine products from Everything Polaris RZR. Companies like CP-Carillo make performance piston upgrades for Polaris RZR 4 engines that are 93mm in diameter with a comp ratio of 11-1/2 to 1. Or if you're looking for connecting rods that are forged and manufactured without compromise, Carillo makes those as well. From Polaris RZR 4 engine valve springs to head gaskets and big bore kits, there's nothing stopping you from achieving unadulterated power when you shop at Everything Polaris RZR! Like Carillo, motorsports firms like Alba Racing are also well-known in the industry for their Polaris RZR 4 engine performance upgrades. They offer level 1, level 2, and level 3 engine rebuild kits, as well as both manual and automatic cam chain tensioners for the Polaris RZR 4. No matter if you have the need for speed, or if you simply want enough power to propel you and your loaded-down UTV uphill against strong headwinds, the engine performance parts and accessories from Everything Polaris RZR will give you the extra horsepower you're after! 

While low-boost Packard Performance turbo kits, aftermarket Trinity exhausts, and high-precision ECU tuners are frequently used by Polaris RZR 4 owners to achieve power gains, to truly open up the performance of your side-by-side's engine, you're going to need specialized mods, accessories, and performance Polaris RZR 4 motor upgrades. Things like cometic top end gasket kits are great, and cylinder head rebuilds can provide a tremendous amount of bang for your buck as well. But whatever it is that you're lacking, be it a billet intake manifold or a high flow water pump impeller, you can increase the performance of your Polaris RZR 4 engine with the products and accessories from Everything Polaris RZR!
