Note: For ease of shipping and installation, this header comes in 3 pieces and is just slipped together, then bolted in place. The factory O2 sensor port can easily be opened up with a power drill before use. Lengthening of the O2 wires is also required.
The oil filter will need to be right up against the block or on a sandwich plate at most. The larger oil filter mount found on later 4AGE 20v will need to be removed with an Oil filter union which we can provide if asked for.
**Headers are now made from Stainless Steel, raw finished. No black coating**
