Spark plugs are something that are often taken for granted. That is until our engine has a problem. Almost everyone has heard of Denso and their roll in the spark plug world. Now, I know what your are thinking “Charles, you are a Euro guy, Denso plugs are for Asian imports”. Well you are right, Denso’s Iridium TT Spark Plugs work awesome in that environment. In fact I ran Denso Plugs in my wife’s Nissan. Denso also makes spark plugs to fit a number of application, and is the choice of tuning companies like NeuSpeed. Denso TT plugs are also on rebate so you can save a up to $16 http://DENSO.rapid-rebates.com

While many of them were simply due to maintenance, there have been plenty of failed spark plugs. Some times that means the spark plug was faulty, other times it was due to the wrong spark plugs being stalled. Installing great quality spark plugs is vital to engine performance, power, and fuel economy

Twin Tip Technology
The technology behind Iridium Twin Tip is less obstruction to the spark allowing an omni-directional explosion. This minimizes the quenching effect and results in a more effective, more complete combustion.  The large center and ground electrodes seen on a Standard Plug increases “quenching” of the explosion, meaning the spark explosion is restricted by the electrodes above and below the gap, allowing it to spread to either side, but not grow with full range. Twin Tip Technology overcomes this with a unique design, there are literally two “tips”: a 0.4-millimeter Iridium center electrode, and a 0.7-millimeter Platinum ground electrode.

There are a lot of aspects of vehicle maintenance and repair that require the proper parts. So whether you are driving a stock Acura, or a modified car, do not let poor quality spark plugs hinder your engine performance and fuel economy.
