Denso Iridium IK27 Spark Plug (1 plug)


Suitable for all Cosworth YB 250 > 500 BHP and CVH (all power levels)Improved Horse Power Get more power with an optimal combustion cycle.IRIDIUM POWER has a low required voltage and a high ignitability, resulting in less misfiring and no spark, the outcome being a dramatic improvement in combustion. Engine output is thus increased. The findings of a bench test using a motorcycle engine to show the improved combustion from IRIDIUM POWER is shown on the below. Compared to normal plugs, a 0.5ps (1.4%) improvement is seen in output at 110km/h.Improved Acceleration Increased response and acceleration performance.IRIDIUM POWER best demonstrates its performance improvement during acceleration.IRIDIUM POWER has a 0.4 mm diameter iridium center electrode and a specially shaped ground electrode. These features combine to achieve higher ignitability and require lower spark voltage than ever before. This enables high-response driving with fewer misfires than under higher required voltage spark conditions, and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.Improved Fuel Economy Even during idling ignition is assured, with less fuel consumption and less noise.The good ignitability from the fine electrode (0.4mm) of IRIDIUM POWER draws out much more performance from the engine. Comparing a normal plug (W20FS-U) with an IRIDIUM POWER(IWF22) on a 2 cycle 50cc engine, fuel consumption improved from 41.74km/L -> 43.69km/L, an improvement of about 5%.Note: Mileage measured using a chassis dynamo; actual driving results under normal conditions may vary.

HT Plug Leads Set for Escort RS Turbo

Motorsport Developments

A full set of 5 HT leads - 4 x spark plugs and 1 coil lead.Fits:All Ford Escort RS Turbos - both Series 1 and 2Please remember, we only supply and fit parts here that are tried and tested by us and are proved to work properly. There are many HT lead sets on the market that are both cheaper,a nd more expensive but unfortunately we remove and throw lots of them away in our workshop on an almost weekly basis and have been doing so since we started tuning these RS's years ago as they do not have the interference suppression qualities that are required to ensure the poor quality 80's Ford wiring looms do not induce interference from them.The fact some of these cheaper leads have well known household names makes no difference, many of them are designed for modern cars with great interference suppression built into the looms and components. Take care, buy right, buy once...
