Sorry so good so far, fitted straight away with no problems and goes well with the msd cap and compared to the old 8mm Impressive

Dear JDMSPEED, Your JDMSPEED spark plug wires looked very good, but the spark plug boots were too small for my 1969 Ford 351 CID Small Block engine. Please send a return label. Thank you Lance Moore.

Great product, very happy with the purchase. This is a combination of different sizes. It can take a while to figure out which length works best with which fork, but after a bit of back and forth it's easy to figure out what works best.

I bought these simply because they were cheaper online than in the store. I installed them on 89 f250 with efi 5.0 and overall they were easy to install and very high quality. Considering my truck is 31 years old and nothing special these cables really make the engine bay crackle!

Excellent set of cables, especially for the money. The only downside is that the material used in making these wires is more comfortable if your car sits a lot, which attracts mice more than traditional wires. I learned this the hard way and had to order another set while dealing with rats.

They claim 50 ohms per foot but testing showed 30-34 ohms per inch? The included 9" coil wire itself had a resistance of over 270 ohms! Their claims are misleading to say the least. They are better than standard core wires for interference rejection, but not by much and definitely not the quality they claim to be. I am not sure if i will bother to return them as i would love to get my btruck back on the road i am just very disappointed.

I was asking about the connectors and spark plugs for a 1965 Mustang. When they arrived I put the spark plug wires aside and just installed the spark plugs. After detailing the motor I attempted to install the connector wires, these wires turned out to be too large a diameter to fit and I missed the return deadline. If there is a way for me to return them and get the right set for them I would be very grateful. Thanks - linzlabit@gmail.com
