Review: Fantastic performance - I installed this on an older 95 LT1 v8 it really helped give it a boost in spark and car runs well. Note this was not a stock engine. It has a large cam, ported heads and Headers. Another note. I also have the MSD coil but still use the stock opti spark distributer. one thing that makes a big difference is using the correct oil seal on the distributer once I finally installed the proper oil seal that looks like a standard oil seal all the problems with the opti spark went away after cleaning the oil out of the inside. Don't need to waste money on a 595.00 MSD distributer. Iv'e only heard bad reviews about them. this opti spark distributer was only 45.99 Review: Awesome product - I received DOA MSD control boxes from desertcart, however the third box I received finally did the trick! At first, I believe it was the installation or how my car was pre-wired, however after calling MSD and troubleshooting with them, I was convinced it was the MSD box. I have a smoother ride, more power/torque felt in the low/mid range, starts easier and faster (it already started great, but you can feel/hear the difference with the digital 6AL). Gas mileage, surprisingly, increased. Well worth the investment. My car is a 1973, Datsun 240Z with triple weber carbs, headers, and pertronix 1 elec. ignition. Please note I changed my Pertronix Coil to an MSD coil during troubleshooting before realizing the Box was the culprit, so not sure, but I doubt if the Pertronix coil is compatible with the 6AL. ## Features - All wires exit through a locked, sealed connector - Efficient components use less current to produce more power - Built-in LED for system checks - Compatible with 4, 6 or 8-cylinder engines - Set an rpm limit with two rotary dials in 100 rpm increments - 12-15 Volts, 7 Volt Start - .7 Amp per 1,000 RPM - High output with 530 volts and 135mJ of spark energy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004EGZU42 | | Best Sellers Rank | #104,140 in Automotive ( See Top 100 in Automotive ) #16 in Automotive Replacement Ignition Control Units | | Brand | MSD | | Brand Name | MSD | | Color | Red | | Customer Reviews | 4.7 out of 5 stars 567 Reviews | | Display Type | Digital | | Global Trade Identification Number | 00085132064250 | | Included Components | MSD Ignition 6425 6AL Ignition Control Box , Red | | Item Type Name | MSD Ignition 6425 6AL Ignition Control Box , Red | | Item Weight | 1.4 kg | | Manufacturer | MSD | | Material | Plastic | | Material Type | Plastic | | Model | 6425 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 6425 | | UPC | 085132064250 | | Unit Count | 1 Count | | Warranty Description | Manufacturer's Limited 1 Year Warranty | ## Product Details - **Brand:** MSD - **Color:** Red - **Display Type:** Digital - **Item Weight:** 1.4 kg - **Material:** Plastic ## Images ![6425 Digital 6AL Ignition Control w/ Rev Control - Red - Image 1](https://m.media-amazon.com/images/I/71xLd8l9nxL.jpg) ![6425 Digital 6AL Ignition Control w/ Rev Control - Red - Image 2](https://m.media-amazon.com/images/I/813a+a-6nKL.jpg) ![6425 Digital 6AL Ignition Control w/ Rev Control - Red - Image 3](https://m.media-amazon.com/images/I/71ckolcM+qL.jpg) ![6425 Digital 6AL Ignition Control w/ Rev Control - Red - Image 4](https://m.media-amazon.com/images/I/71CiinNHnnL.jpg) ![6425 Digital 6AL Ignition Control w/ Rev Control - Red - Image 5](https://m.media-amazon.com/images/I/71-wAP-MtSL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does it work for the suzuki esteem ??** A: THIS MSD BOX WILL WORK WITH 4,6, & 8 CYLINDER ENGINES. **Q: With this installed, will it need to be tuned or can i just change the timing?** A: This is just the ignition box **Q: Can the Rev limiter be used on a fuel injected engine ? 1990 Mustang.** A: Yes it can, it controls the spark. **Q: Why won’t Amazon ship this item to me in California?** A: But it IS legal in California. https://ww3.arb.ca.gov/msprog/aftermkt/devices/eo/d-40-43.pdf ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic performance *by B***S on August 14, 2019* I installed this on an older 95 LT1 v8 it really helped give it a boost in spark and car runs well.
