02-05 Civic Si Skunk2 Valve Springs
Skunk2 Racing valve springs are made from the highest quality chrome silicone wire from Japan. These valve springs are designed from our experiences in touring car and drag racing. The dual interference fit valve spring design prevents harmonics and valve float. All valve springs are race tested and proven and can be used with both forced induction and naturally aspirated engines.
Note: DUAL SPRINGS
ENGINES EQUIPPED WITH SINGLE SPRINGS WILL REQUIRE NEW DUAL SPRING BASE AND TI RETAINER KIT.
