If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. A cold spark plug is designed to operate at higher than average temperatures and disperse the heat inside the cylinders, improving combustion, performances and engine reliability, reducing the risk of detonation.

According to NGK the size of the standard gtr plug is the same as the BKR so I cant see any reason why they would not fit.

Under no circumstances will we accept liability to you in respect of costs incurred such as: (but not limited to) loss of earnings, travel expenses, recovery costs, damages etc. reduces the heat at the surface of the spark plug, which can become a hot zone and a cause of detonation.

Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties - no anti-seize lubricant needed!
