Upgrade your tuned NA engine with 284ø/276ø cams for improved mid-high rpm power. These cams are perfect for rally and circuit racing, but you must have free flowing intake and exhaust upgrades in order to make the most of them. They work best with a higher compression ratio and will pull to around 8-8.5k rpm depending on your engine.ÿ
- To maximize the benefits of these cams, Kelford Cams recommend using the KVS109-3S valve spring.
