Product Details

The Advanced Engine Design 5025A is a high-flow, four-door power valve specifically designed for alcohol fuel applications in Holley-style performance carburetors. This single-stage power valve opens at 2.5 inches of mercury (Hg) vacuum to activate the power enrichment circuit, delivering additional fuel when engine load increases.

Key Features:

  • Four-door high-flow design provides greater fuel flow capacity essential for alcohol and methanol applications
  • 2.5 in. Hg vacuum rating ideal for high-performance and racing engines with lower manifold vacuum
  • Single-stage operation with quicker response rate for precise fuel enrichment tuning
  • Compatible with Holley 4500, 4150, 4160, and 2300 series carburetors
  • Includes gasket for proper installation and sealing
  • Hand-tested to ensure accurate opening point at stamped vacuum rating

The four-door design features four fuel delivery ports instead of the standard two-window configuration, allowing significantly higher flow rates required for alcohol-fueled engines. This enhanced flow capacity ensures adequate fuel delivery during the power enrichment phase, enabling engine builders to fine-tune carburetor performance for maximum power output. Proper power valve selection is crucial for optimal carburetor tuning, and AED's alcohol-specific power valves are engineered to handle the unique fuel demands of methanol and alcohol racing applications.

Very pleased with my purchase and Autoplicity. Got the best price on the internet and received it very quickly. Product arrived just as discribed. I highly recommend Autoplicity for your on-line shopping needs.

I like this site has very low prices and great products

Awsome service and prices,Thanks alot

Great to deal with both online and over the phone. Buy with confidence.

Great prices and super fast shipping. Found my new online parts store!

Simple checkout process

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.
