HKS RB26 STEP 1 272 IN (N) - 2202-RN126

The HKS RB26 STEP 1 272 IN (N) is a performance intake camshaft engineered for the Nissan RB26DETT twin-turbo inline-six, the engine found in the Skyline GT-R lineup. Part of HKS's STEP 1 camshaft series, this intake cam is ground to extend the usable rev range and improve top-end airflow over the factory grind, making it a popular first step for RB26 builds looking to unlock more power while keeping the engine streetable.

Key Features & Benefits

• 272-degree duration intake profile increases valve open time for improved high-rpm airflow and power potential versus the stock RB26 intake cam
• 8.7mm valve lift opens the intake valves further for better cylinder filling at higher engine speeds
• 110-degree valve timing specification is tuned as part of HKS's STEP 1 cam series for a broad, useable powerband
• Manufactured by HKS, a long-established name in Japanese performance engine components, for consistent quality and fitment
• Pairs with the matching HKS RB26 STEP 1 272 EX exhaust camshaft for a complete intake/exhaust upgrade on RB26DETT builds
