Brisk Silver spark plugs
A spark plugs ability to ignite fuel in different circumstances effects a cars performance drastically. Low quality or clogged plugs dont ignite fuel properly, and instead of producing engine power, some of the fuel mixture is simply flushed into the exhaust. Where mainstream brands usually focus on low costs, Brisk's focus is on quality plugs.Silver is the best conductor for electricity and heat.Slim silver center electrode.Superior ability to ignite air/fuel mixture.Works witl low voltage coils as well.For competition engines and hard-to-ignite fuels.Common plug shortlist

For stock cars, get the OE heat rating. Mildly tuned (exhaust, filter, etc.), get one step colder, and with more boost / cams or other serious tuning get two steps colder.
In Brisk heat ratings a higher number is hotter, and a lower colder. Most stock plugs are 14 or 15 in the Brisk range. Here is a spark plug heat range comparison chart.

For a tuned car, you should use the stock or one step colder plug.Our import program doesn't include the ZC model. If the catalog suggests DR14ZC for your car:
» DR14ZC or LR14ZC plugs can be replaced by DOR14IR (iridium) or DOR14LGS (quad tip) models.
» DR15ZC or LR15ZC plugs can be replaced by DOR15LGS (quad tip) mallilla.
» We suggest Iridium Racing (IR) for all older cars without direct ignition and tuned cars, and LGS for new/stock cars with a direct ignition (coil on plug) system.
