THE GROUP BUY IS NOW CLOSED. UPDATE: The V8 housings available have all been claimed. A coupon code will be sent to those that got on the list before Monday the 11th at Midnight PST. Any other sign ups will be added to a pre-order list for when Brian gets the next set in stock. Brian has offered to do a group buy on the billet filter housing: Billet Oil Cap for filter Billet aluminum oil filter cap The discount will be 1% for each purchased up to a max 15% discount. The group buy is cross promoted at TacomaWorld and T4R.org for the V6 cap as well, which I will track and update. I have this installed on my 200, and it makes oil changes a lot easier. UPDATE: We are already over 15 in under 24 hours (not surprising for a great product). The GB will run through Monday December 11 at Midnight. I will PM each of you that signed up with the code. I will confirm with Brian how long the code will be active. Assume we can get 15, the cost looks like: Housing only: $105-15%=$89.25 Housing with valve only $129-15%=$109.65 Housing with valve and socket $145-15%=$123.25 Prices include shipping from what I can tell.
