MSD 6425 Digital 6AL Ignition Control w/ Rev Control - Red

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

I received DOA MSD control boxes from Amazon, 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.

muy buena trabaja correctamente

Quality Duraspark ignition upgrade for my 1988 Jeep YJ Wrangler 4.2L. Lots of YJ owners go with an HEI distributor but I preferred to keep my original Duraspark distributor and use the Digital 6AL MSD Ignition because it is much better quality with more features and benefits. Some of those include, multiple spark, built in adjustable rev limiter, powerful spark at higher RPMs, lower voltage needed for cranking and extras like the capability of later adding the Adjustable Timing module if you find the need to retard/advance on the fly. If you’re really serious about your Jeep and want a top notch ignition, look no further the MSD 6425 is the perfect box for your ride.

Recomendado!!

Finally installed. Had to replace my older 6al box (fried beyond repair according to MSD when I sent in to be refurbished). Same wire combo. Does seem to be running much smoother then my previous box. Have not drove car yet. Still adding some final touches to it before it is road worthy again. I know MSD says no fuses are needed. But since this is my 3rd box in 15 years (due to being fried) I added a inline fuse for added security.

I have to say, This is a very good product.Install is easy. My car starts easier and runs noticeably better at idle and through entire rpm range. My only prob is that I can't change my rpm limit without a ecu reflash. This rpm limiter will work on older cars. I haven't tested it out to see if it will cut at a lower limit than my stock one for s***s n giggles to make sure it actually works. Besides that there are no issues.

Works as it should

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

Works awesome. Took a minute to figure out the rev limiter but works like it should.

solo funciono un poco mas de un mes y fallo

Bought this one because my old one was acting up, now my old one is my back up. Shopped around a lot for this item, this one from this vendor was the best value.

no funciona el encendido electronico y no se donde hacer la devolucionMe pueden orientar por favor?
