BRISK Silver Racing LGS Multispark Plug – DOR15LGS.
More Power - Better Acceleration !

The BRISK Silver Racing LGS DOR15LGS is a high-performance Multispark plug developed in close association with Lamborghini for their naturally aspirated racing engines. Unlike conventional plugs, the LGS (Laser Ground Strapless) design eliminates ground electrodes, ensuring unrestricted flame expansion and superior ignition efficiency.

Originally tested and developed in Lamborghini racing programs, the DOR15LGS is now available for high-performance road and motorsport applications worldwide.

🔹 Advantages Over Standard Racing or Iridium Plugs

• High-Potential Semi-Surface Discharge → More Power
  Delivers maximum spark energy with semi-surface discharge, ensuring strong ignition at every combustion cycle.

• 360° Ignition Zone
  Ignition occurs at the richest point of the mixture in a 360° perimeter, unlike standard plugs restricted to a single electrode.

• Patented Electrode-Free Firing Tip
  No indexing or electrode wear issues – perfect for tuned or high-RPM engines.

• Superior to Iridium Plugs
  While iridium plugs focus on longevity, the BRISK Silver LGS emphasizes performance gains, combustion speed, and throttle response.

• Silver Center Electrode
  Silver is the best thermal and electrical conductor, ensuring faster heat transfer, cooler plug tip temperatures, and consistent ignition – ideal for both petrol and LPG/CNG.

• Extended Life in Racing Conditions
  Retracted, integrated ground paths mean no erosion at extreme temperatures.

🔹 Applications

The BRISK DOR15LGS is suited for:

• Performance Cars: Lamborghini, Audi, BMW M-series, Porsche, Skoda vRS, VW GTI, Honda Type-R, Ford EcoBoost, and other tuned petrol engines. However, pls check your original car code for cross reference under Indian car specs. Honda City, Jazz, BRV, Amaze, Elevate, Gypsy, Santro, i10 1.1 Era, are some common Indian cars using the similar plug code where DOR15LGS can also be used. 

• Daily Drivers Wanting Performance Boost: Works as a direct replacement for standard plugs in cars running on petrol, LPG, or CNG.

• Motorsport Applications: Track racing, rally, drag, and endurance setups where ignition stability under extreme conditions is critical.

🔹 Why Choose BRISK LGS?

The LGS plug family was originally engineered to meet Lamborghini’s demand for higher ignition reliability at extreme RPMs and temperatures. The absence of a traditional ground electrode removes the restrictions of spark travel, allowing the flame kernel to propagate freely and deliver explosive combustion with maximum efficiency.

This unique design has since been adopted by tuners and enthusiasts across the globe, making BRISK LGS one of the most advanced racing spark plugs available.
