These guys are great to deal with! Excellent communication back and forth and customer service. Looking forward to bringing more business to these guys!

I would recommend them for all your LSX oiling needs

Perfect, super quality, thank you !!

I really like this company. They make high quality racing products for a fair price and offer excellent customer service.

Great service. Acceptable pricing. Parts you need to improve the oiling system of your LS engine. Very pleased thus far in my dealings with them!

Lots of items for GM vehicles. Good pictures of the items. Quality products that incorporate good features. I purchased an oil bypass valve for an ls6. They are common valves but improved had the one with a thermostat so the oil will only go to the cooler once it's hot. Received the item quickly with hardware i need to install.

I installed the VCM otr Intake on my 2009 g8 gt. The fit, performance and prompt delivery was all perfect! It looks much better than any other intake out there and gives the engine compartment a clean finished and aggressive look. I have the upgraded new version that has excellent changes in preformance, durability and apearance. I did have to slightly modify new pcv tube by slightly pointing it up to help clear the power steering resevior, or the tube wouldhave kinked. Then trim the engine cover around the tube, and it looks great! Still NO complaints here. It's the best intake out there and werth the money!

I have ordered from them three times as of this writing. Each time they delivered quality products quickly. The prices for both their products and shipping are reasonable. I would definitely recommend them.
