Supertech Valve Stem Seal for Nissan GTR 350Z 370Z Skyline

Supertech 6mm valve stem seals fit many Nissan engines including R35 GTR, 350Z, 370Z, Skyline, Sylvia and more. Sold individually as needed, price is for ONE seal, please confirm your quantities.

The seal size is the same for intake and exhaust. Typically we use the blue exhaust seals all around as they have the highest heat rating, but the brown intake seals are just a touch cheaper. DO NOT use the intake seals on exhaust valves. The blue seals have a higher heat rating at 475° vs 300° for OEM.

• Guide OD 10.03mm
• Seal OD 12.6mm (.495')
• The intake seals are brown (Polyacrylic)
• The exhaust seals are blue with an extra high temp additive (Viton Rubber)
• Both have a 6mm diameter
