This is a new product from Visconti Tuning which is unlike anything else on the market. This valve cover modification prevents the internal PCV from failing. When the PCV system fails the end result is a broken valve cover a smoke. If your valve cover is not damaged you can mail it in and we will upgrade and send it back. If you have already broken you valve cover we have new units on the shelf which we can send you. Turn around time is normally 2-3 days. Please note that this product is not a returnable item, all sales are final.
