SET OF 4 VMS PRO SERIES RACING REPLACEMENT COILS that will fit in place of your stock 2002-2011 Honda Civic Si/SiR 2.0L coils and will directly connect to the factory connectors. These coils will deliver 15%-20% more spark energy for improved power and performance. Increased spark energy and voltage, help improve the combustion process of the fuel mixture to create an efficient burn. The result are quicker starts, improved idle, improved throttle response, cleaner plugs, cleaner emissions plus increased high rpm performance!
These ARE REAL HIGH PERFORMANCE COILS. These are not just cheap coils with red coloring! You can not manufacture a set of high performance coils and sell them for $4.50 each, it is NOT possible. These coils have more turns ratio (56:1) and a lower primary resistance to be able to produce a high voltage output. We use the same factory to make these coils that the big name ignition guys use. The price is better as you are buying directly from the manufacturer and the product is not going through multiple hands before you get to buy it.
