Thank you. You have rated this product.

Racing Beat's ULTRA 8mm wire sets, with noise suppression shields, for street-application 1971-85 12A and 13B engines are constructed with zinc-plated high-strength copper wire to prevent corrosion. Threaded brass connectors are crimped to all wire ends to provide a superior connection. The silicone rubber used will handle over 100,000 volts and is capable of withstanding temperature ranges from -60 F to +480 F over exceptionally long periods. ULTRA Ignition wire sets have a wire wound resistor encapsulated in each spark plug boot. This feature reduces electromagnetic radiation.

To obtain reasonable horsepower gains while curbing radio interference from your ignition system, we recommend the use of resistor spark plugs with our ULTRA 8mm Street Ignition Wires. To obtain maximum power gains from our ULTRA 8mm Race Ignition Wires, we recommend the use of non-resistor spark plugs.

Each wire set is assembled "in-house" by our Racing Beat technicians using the high quality ULTRA ignition components. Produced in Japan, these components are hand-assembled for each specific application that we offer. Each set is assembled and test to ensure correct resistance prior to final packaging. This custom assembly process provides us with complete control over the entire assembly procedure.

Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!
