  • BMW S58 (M2, M3, M4 G8X, from 2021) engines

What to check

  • The camshafts keep full Valvetronic and double VANOS function, so idle and drivability stay smooth.
  • They are machined from forged solid 8660 alloy steel blanks, rifle drilled, induction hardened and CNC ground, with a thicker barrel wall than stock; the OEM camshafts can bend when the engine is pushed.
  • They work with the stock springs, but Skunk2 recommends the 313-14-1000 spring and titanium retainer kit, as long-term durability on stock springs is unknown.
  • The engine builder must check piston-to-valve clearance and set the minimum exhaust centerline for each combination: over-retarding the exhaust cam causes piston-to-valve contact.
