Has anybody used these. I know sportruckspecialties.com has them for the V6 Tacos and I think unorthodox racing also has them , also can they fit a 2003 Tundra 3.4

It seems that you are putting up tons of posts asking about all kinds of things that are going to give you little if any improvement in performance and in the end is going to cost a good bit of money.

Have you thought about installing a TRD Supercharger? If you add up the cost/benifit ratio, I think you may find that it is a good deal if you can find one for a good price.

Then all you will need is the fuel injectors, fuel pump and a controller like the FTC or UNICHIP and you will have a very nice performaning truck.

I have Thought of the TRD S/C but at $1999.00 thats out of my price range. All the mods I ask about are very cheap or under $300.00 thats with in my price range. Don't get me wrong wpuld love to have a TRD S/C but since I am tight on CASH I have to hold out on the S/Cp.s I am saving for the S/C hopefully I will have one year.
