Interesting product...Are they the only ones that make it? Couldn't tell much on performance improvements....










Link here:
LEMS Throttle body for USC10/URL10

 

We have access to LEMS products.

They do not list much info other than it requiring trade-in.

.. but it looks similar to Think Design Big Throttle Body (for RCF) which has the following features:
- Bored 2mm (5-10% air flowincrease)
- Titanium butterfly for more response
- Low profile butterfly bolts and bracket for smoother air flow

Price is ~$850 for the LEMS BIG Throttle Body (requires trade-in). I will try to get more info on the features.

There are people in the USA that bore throttle bodies for much less, but I didnt see anything about titanium butterflies or low profile hardware, although it may be possible on request.

 

www.maxbore.com is another, more cost effective alternative. If you don't have a core you will need to send your TB in which will require downtime.
