Warranty Details (Limited Lifetime Warranty)
NGK variable pitch resistor cables provide uniform resistance and ensure outstanding electrical conductivity in high-quality cables. Outer EPDM/silicone jacket and inner insulation contain high voltage currents for excellent dielectric strength. NGK variable pitch magnetic core cables produce the necessary impedance to suppress interference throughout the entire frequency spectrum for exceptional EMI/RFI noise suppression. OE or better specified spark plug and distributor boots ensure the highest quality fit, performance and durability in every application. Spark plug boots are glued to NGK cable with a silicone sealer for a watertight seal. Stainless steel terminals utilizing up to 3 serrated crimps bite into cable jacket and inner insulation for the highest terminal retention strength (wherever possible). Locking C-shaped spring clip with corrosion-resistant plating ensures a secure and positive spark plug terminal connection.

Replaced new 'cheap' wires, FIXED SKIP!
NGK or DENSO for Jap cars ONLY! PLUG AND WIRES! NGK OR DENSO ONLY!
Again I had a customer with BRAND NEW '7mm House Brand' Wires he got at the Auto Parts Store. The engine missed a little at idle, ran perfect the rest of the time. He had NGK plugs at least.
I told him its the other brand wires, he did not belive me... He does now. These wires made the car idle like it is suppose to, smooth. Like stock!
Buy these for your Jap CAR!

Spark Plug Wire Set
Had to return the spark plug wire set because one of the caps would not seat defective out of box. Problem was stores close at 8 PM by the time I realized there was an issue store was closed could not drive the car till the next day. Thankfully I have another car but if I did not would have been in a hurt.
