Q: I have an HKS Super Mega Flow intake kit, is it SMOG legal?

A: HKS Super Mega Flow kits with the "1504" part number prefix are CARB exempt with the CARB Executive Order # D-186-19.

If you did not receive a CARB EO exception sticker with your HKS SMF intake kit and the kit is an CARB exempt kit (some racing kits are not CARB exempt), please contact either the dealer whom your purchased the kit from or our tech line at (310) 491-3300 for information on obtaining the sticker.

When contacting us, please have your purchase receipt available to fax in and our techs will be able to support you in the information that you require.

Thanks!
