GrimmSpeed Tumble Generator Valve (TGV) Deletes for 02+ WRX/STi & 05+ LGT

Highest Quality TGV Deletes that anyone can afford!

Dont feel like spending $500 for a new set up butterfly-less tgvs or $600 for a JDM Intake Manifold? For less than 1/2 the price you can get the same exact benefits from our TGV Deletes. In this process we take a stock TGV and completely gut it, which includes taking out the metal plate, butterflies, and bar. These will allow for maximum flow through the TGV. Minimize the engine's heat from entering the TGV's with our ceramic coating. It is very important that heat stays out of the TGV's because this is the last transfer before the intake air enters the engine. Cooler intake air equals more hp.

Customers have seen gains of 15+ whp/wtq. We've also seen third party flowbench tests showing an increase from 330 cfm to 480 cfm!!

On a typical STG 2 setup you are going to realize an increase of 5-10tq/5-8hp in the low end, 10-15tq/8-12hp in the mid range, and 5-10tq/5-8hp at the high end. As you can see in the dyno graph, max gains are going to occur in the mid range. As far as where the gains occur in the power band, yourentire power band is going to see an improvement with our TGV Deletes.

These will also give you a quicker turbo spool up. If those gains weren't good enough for you, wait till you add a bigger turbo...the bigger the turbo you put on the bigger the gains are going to be from getting the GrimmSpeed TGV Delete.

IMPORTANT NOTES:

1.) As always, if you are not sending in a core to get deleted, you will need to pay the core fee. You will get this money refunded when you send your old stock pieces back to GrimmSpeed.

2.) If you choose to send in your OEM TGV's to be ported rather than buy ones already done, please allow about 2-3 days turnaround time for GrimmSpeed to do their services. Once completed, GrimmSpeed will then ship out your ported TGV's back to you. 2a.) Please allow an additional 1-2 days if your getting your TGV's ceramic coated after being ported.

3.) Our "Shipped" Price below includes neccessary shipping costs to ship "yours" or "GrimmSpeeds" TGV deletes from GrimmSpeed to you (the customer). Customers will be responsible for shipping costs to either... ship their OEM TGV's to GrimmSpeed to get ported... or the shipping fees to ship back a core after recieving the GrimmSpeed TGV delete. It works out the same for whichever way you choose.

4.) If you order 3mm Phenolic Spacers you can re-use your oem hardware for installing your intake manifold. For 8mm Phenolic spacers longer bolts are needed to install your intake manifold and are included with your order.

If you have any questions about the shipping and/or the services being performed, please feel free to contact us.
