Super Conductor Spark Plug Lead Set8.5mm, Black, Universal 8 Cyl Multi-Angle Plug/90° HEI Distributor Cap Terminal
Brand: MSD
Part Number: MSD31183
Description:
  • Copper alloy conductor has a resistance value of less than 50 ohms per foot for superior spark
  • Ferro-magnetic impregnated core creates an effective EMI choke
  • Forty feet of conductor is wound into a single foot of wire for high EMI suppression
  • Conductor core features Dupont Kevlar material for increased tensile strength
  • Durable outer sleeve is a proprietary compound for resistance to high heat or abrasion

The MSD 8.5mm Super Conductor is the ultimate performance wire! Its extremely low-resistance combined with the ability to suppress Electro Magnetic Interference is a combination that defies the common laws of physics. Less resistance means more energy is going to make it to the spark plug to ignite the air/fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less than 50 ohms per foot of wire! This e ssible makes it to the spark plug. This combination is encased in a heavy duty sleeve that will withstand abrasion and high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best wire available!

Works like it should, easier to use if you keep the dosing funnel on the basket
Color: Black, Color: Black
With a weighted top and storage base, this is sturdy metal with what appear to be standard acupuncture needles. It comes with a set of spare needles in a plastic tube. I find it much easier to use if I keep my dosing funnel on the basket, followed by a quick clearing of the funnel using a weighted espresso distribution tool with the maximum extension before popping off the funnel for my final tamp. See photo.

Simple tool that makes a difference
Color: Black
This tool really improved my espresso. It’s easy to use and helps distribute the coffee evenly, which makes the shots come out better. It feels solid and well made. Small but very useful.

It's not bad, but one minor issue FOR ME
Color: Black
There is nothing generally not to dislike about this WDT. Priced right. Good quality materials. But there are two issues that made me choose a different one, even before using this one: The entire top and bottom are straight cylindrical pieces. Ergonomically I would have to use more, larger muscle movement from my wrist to stir the beans. Not a big deal for some, but with other similar choices at the same price, I thought I would be better off with a different model. The second issue is that then the needles are placed back in the tall "recepticle", the top piece merely sits on top and isn't secured. For some that might be good because the top can be lifted out without any opposing force. OTOH, if it tips over it might expose the needles or need two hands to get it back together. If I didn't have other choices, I'd keep this one. I knew, without even using it that it wasn't for me... but it might be for someone else. Again, the materials are quite good and you can tell by the heft of the item. I elected to go with a similar concept, but a more contoured design with a knurled top and brushes on the inside of the recepticle to hold the needles and top in place, but also easy to extract for use. My choice over the Tiverain WDT was personal and has nothing to do with the quality of the product.

High quality and looks great
Color: Black
Works well, definitely deep enough. I like the stand- ease of lifting it off its base and then returning it without needing a second hand. Has a modern sleek look and it’s heavy in a good way. Feels like quality build.
