Product Details

The Supertech Performance BG-QR25DE Block Guard provides critical support for highly stressed cylinder walls in Nissan QR25DE engines, particularly in high-performance and forced induction applications. This precision-engineered component helps prevent cylinder wall flex and distortion under extreme conditions while maintaining optimal engine cooling.

Key Features:

  • Constructed from high-strength, corrosion-resistant 6061 aluminum alloy for durability and longevity
  • CNC machined to exacting tolerances for precise installation and optimal fitment
  • Engineered coolant passages allow adequate water flow in critical areas to prevent destructive hot spots
  • Reinforces cylinder walls to minimize bore distortion under high boost and extreme cylinder pressures
  • Meticulously designed and tested specifically for the QR25DE engine platform

Block guards are essential for serious performance builds running high boost levels, where cylinder wall movement can compromise head gasket sealing and lead to engine failure. The Supertech BG-QR25DE balances structural support with proper cooling, making it ideal for turbocharged builds on the popular Nissan QR25DE four-cylinder engine found in Altima, Sentra SE-R, and X-Trail models.

Part was excellent! Work as advertised..

easy

This site is easy to navigate.

Came a day later than I expected. That's all

I need new windshield wiper blades and Autoplicity had the brand I needed at a good price and was able to confirm they would fit my car make and model.

Awesome job guys! communication was super fast! price was cheap and shipping fast! definately do buisiness with these guys again

was satisfied with order

Really couldn't beat the price, I tried to find a better price and couldn't. I just wish it didn't take so long to ship it. I placed my order 4 days ago on a Sunday night hoping to get it by Saturday. They just shipped it today on Thursday. So now I have to wait through this weekend and next week. I ordered other things from different companys on the same day and received from them already. So I guess that's price I pay for a good deal.

Easy to navigate to choice of parts

the best

Best price by far! Fast shipping!

Easy

ordering was simple, paying was very quick and easy with amazon.

Excellent prices. Reasonable shipping. Website is a little tweaky but if that keeps prices low who cares!

Was going to also order TCI-618008 with this purchase but the free shipping didn't apply? Just thought you could add it to the same free shipping box.

Sitting at home, having a beer, ordering parts and saving money, can't beat that!!

Finally I found the part I have searched all over for. Thank you autoplicity for having such a specialized part. Great customer service too. Very easy to use web site as well.
