Injected Performance is our primary storefront for retail and wholesale car parts for most makes and models. With brand names ranging from AEM to Yokohama and everything in between, we offer over 7,000 products for sale. Even if something isn’t listed, chances are high that we can still offer it anyways. Through the Injected Performance storefront, located in Lexington, KY, we are also able to offer the following services:
- Dyno Tuning - Our in-house 2WD Dyno Dynamics dynamometer can measure up to an estimated 1500whp. Whether you want a quick benchmark or an all-day tuning session, our dyno is full of features to help you. We currently support: Haltech, AEM, HP Tuners, and Unichip. Please contact us for additional tuning questions.
- Engine Building - Following the success of our own racing engine builds, we offer a variety of levels of engine building services to help meet your power goals. Whether it is a stroker motor or custom turbo setup, or both, we have the resources to help you obtain as much power as possible.
- Product Development and Testing - Through the years of experience we have with Nissan’s VQ35 and other engines, we have been able to develop many products that have withstood the tests of our own 350Z race car. Most of these products, such as solid motor mounts, upgraded fuel rails, and billet main girdles, are available for sale.
- GTRMod.com
GTRMod.com is a subsidiary site dedicated to helping you shop for aftermarket items for your new Nissan R35 GTR. As products are developed and released, we offer the latest and greatest modifications at our usual low prices. Our own GTRMod.com Nissan GTR can be seen in detail here.
- 350ZMod.com
350ZMod.com is a subsidiary site developed to narrow your shopping down to parts exclusively for the Nissan 350Z and Infiniti G35. We have personal experience with using and installing most parts listed on this site in order to ensure you are choosing among the best aftermarket options in the industry. However, if there is something you are looking for and cannot find, we will be happy to source it for you.
- Evo8.com
Evo8.com began as a site exclusively for Mitsubishi’s Lancer Evolution 8. Over time, we have added a wide array of products for all Evo generations, including 8, 9, and the all-new Evo X. New products are constantly being added for the new Evo X, and we focus on only the highest quality parts for the Evo 8 and 9.
- HaltechParts.com
We are so proud to be one of Haltech’s leading distributors in the US that we have opened an entire site dedicated to offering Haltech’s entire lineup of ECUs, harnesses, and accessories. We strive to keep every item in stock at all times. Wholesale accounts are welcome and encouraged for fast and easy ordering.
- Walbro255.com
As one of the leading sellers of Walbro fuel pumps in the US, we want to quickly and easily offer the entire line of Walbro high performance fuel pumps and installation kits at discounted prices. Almost all popular applications are kept in stock. Additional Walbro products, such as OEM replacement pumps, can also be sourced by contacting us.
