Engines; w/Soft Touch Rev Control; Red; Review: 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: Muy buen producto recupera entre 10 y 15 caballos, las conexiones simples y de muy buena calidad vale la pena la inversión para actualizar el encendido de un clasico ## Features - With soft touch rev control - Higher output with 530 primary volts and 135mj of spark energy - Efficient components use less current to produce more power - Set an RPM limit on the 6AL with two rotary dials - Same bolt pattern as the original 6AL with a lower profile housing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004EGZU42 | | Best Sellers Rank | #101,276 in Automotive ( See Top 100 in Automotive ) #4 in Car Ignition Control Units | | Brand Name | MSD | | Color | Red | | Customer Reviews | 4.7 4.7 out of 5 stars (541) | | Display Type | Digital Display | | Global Trade Identification Number | 00085132064250 | | Included Components | Ignition Box | | Item Type Name | MSD Digital 6AL Ignition Control PN: 6425 | | Item Weight | 1.4 Kilograms | | Manufacturer | MSD Ignition | | Material Type | Plastic | | UPC | 085132064250 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** MSD - **Colour:** Red - **Display type:** Digital Display - **Item weight:** 1.4 Kilograms - **Material:** Plastic ## Images ![Ignition 6425 6AL Ignition Control Box, Red - Image 1](https://m.media-amazon.com/images/I/71xLd8l9nxL.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 ### ⭐⭐⭐⭐⭐ Review *by B***S on 14 August 2019* I installed this on an older 95 LT1 v8 it really helped give it a boost in spark and car runs well.
