Any way to see the shipping charges on their website before you enter checkout?

Anyone had luck with these guys? Their website reminds me of the way I ordered my Minidisc player from japandirect.com in 1999 haha. Even with shipping they are noticeably cheaper than North American suppliers but who knows, put your order in and just hope it shows up in a couple of months?

Just add to cart and enter in address etc and it will give you a shipping rate before you ever complete the order.

No they are legit, bought a few things from them now. Only bad thing I can say is most items are expensive and so is shipping. But they ship fast and communication is good!
So as long as you don't mind paying through the nose for your hardware and shipping, then I would say your good to go :thumbsup:

Thanks! yeah some of the "readily" available parts (STI, OEM, HKS etc) seem to be priced pretty high but the tougher to find JDM brands are VERY well priced. Might order some Kakimoto and Chargespeed stuff.

Looks Legit. But not into my design scheme. Maybe somebody installing a Turbo or Supercharger might benefit.

What kind of an increase would this provide typically?

More volume of air entering the engine at one time.

Note sure because if the 4 runner section are calibrated for the original throttle body and so are valve and so on. then ZERO gain.
You have first to proof that the Throttle body is the bottle neck.
But I doubt it as it is already very big for a 2 liter engine

Yep. I can see people with force induction options benefiting more from this. From my own datalogging, this engine does not bode well with more volume and no tune. More volume by diameter increase only, lowers air velocity, thus leaning the car out. That is, using a bigger diameter through out the whole intake system too, thus the MAF area is also bigger. That's my own observation.
