FordIgnition Spark Plug Wires M12259R301 45D Red

Works great.

1994 Ford Mustang GT 5.0L I don’t know why I didn’t get these sooner. They’re numbered but still, replace one by one. Wires for cyl 4 and 8 were a little tough to push on but I am using old y303 heads that have angled plug holes. I’ll just assume that was my issue

Provide great power to the plug, fit well (tho a little long, better than being a little short) and look great under the hood. Comes numbered as well which makes life so much easier trying to route the wires and having the correct wire attached to the correct post on the distributor. I also got some of those plastic wire holder things from the auto part store to keep everything organized and looking pretty. 1992 5.0 F150

Nice visually, works great. The wires are numbered but I flipped a couple of them because length worked better. I also shortened #1 wire about 1.5".. for looks. But regardless, the wires will work and fit the way they are numbered.

Fit perfectly on my 1996 f150 302. Love the numbered wires and love it came with 2 different coil wires and lengths

I just finished installing this set (M12259R301 45D Red). I wasn't sure if these would fit, but they do. My distributor is the HEI red one that I believe is the GM type. I marked the rating a 4 star because I felt that 2 of the wires were a little short, but I made them work by creating my own routing and disregarded the numbers on the wires. Also, I felt that I had to pinch the connectors a bit to get them to snap on the distributor better. The color is a nice red, deeper than what the picture shows. Nice heavy wires. I am happy with the purchase.

Nice set of thick quality spark plug wires. So much beefier than the ones I replaced and the lengths were perfect for my 1995 F-150 5.0. Only complaint is that once I got them installed and routed the way I wanted them they were pretty dirty from the 26 years worth of gunk in the engine bay so I cleaned them with some degreaser and a microfiber and some of the white Ford lettering started to wear off. Not a big deal just a bit disappointing. Update October 2025: Still working great and have zero signs of damage or degradation.

I love the way the red looks under the hood! it really accents the American Flag Paint job. Wires were easy to snap on and hook up, they are even numbered which makes it easy. July update: I mean they’re still working but when I took them off to put in nee plugs the metal piece keeps coming out of the plug wire and the boot actually came off the ignition wire. I am going to try another brand see if they’re made any better

Great product been using them for 2 years now no issues or concerns

Ford racing cables de bujía son excelentes conductores que aportan mayor conductividad. Funciona muy bien en mi ford mustang 5.0 ho. Completando el kit de potencia junto con la tapa y rotor, msd ignition 6al y la bobina msd.

These were really good, they are sized right allowing a tidy install

BUENOS, pero en realidad ninguna diferencia contra algunos chinos de buena calidad, estos son hechos en china

Great quality and works for 1995 F150 5.8L
