Collection: Head Stud Kit

This is very good quality and the shipping was very quick. Definitely trust this site and will do business with SPELAB again.

Customer service support was great, and the product worked as described and the extra heater hose included was a life saver in helping me fix my HVAC heater when the factory connector broke.

I am happy with my purchase. Looks to be a quality part, and definitely can’t beat the price .

Looks pretty%2C install wasn’t bad other than the very last fuel line which isnt spelab’s fault lol%2C i find that the turbo spools faster and power comes in harder. Less black smoke now that she can breath%21%21%21 Overall very pleased%21%21%21

Had it installed on my ‘99 Camaro Z28. Sounds really nice at WOT, and the tone is very deep at idle. Was decently made, electric motor has held up nicely from water over the past few months. Wireless fob has better range than my cars keyfob lol. Assembly was straight forward, but there were more parts included than the instructions had said. Would buy again for another vehicle with a v8.

I love this product. Easy install. All hardware was perfect. It’s a beautiful product and has qualities that I love. Fill and drain plugs and mostly the sight port.

Awesome product and very easy to install also the best part about this kit is that it does work with other added on fuel filter AFTER the cp4 so you get best of both worlds🙏🏽

The 5' exhaust with the 6" tip looks and sounds really good. The egr delete its made really nice and fits perfect and looks good.
The ccv it's easy to install it fits and looks good too. Thanks soo mutch

It works great, the nut that rubbed a while in the up pie was moved from the original place and doesn’t rub anymore

Not to easy if you don’t know what your doing\not mechanically inclined, but definitely worth it for the quality love the stuff!

Glad your product is on the market. I love the looks of it and the performance aspect of the intake horn. Glad I chose ya’ll. Can definitely feel the truck breathing better!!!

Overall, great kit. Wish I would have ordered the can bus plugs at the same time. A few modifications were needed to make everything work but nothing too difficult if you can tackle this type of work to begin with.

Great quality and fit

With my old kit that kept leaking, an abnormal seal size and changed colors as the plastic got warm. I installed the Spelab kit and fits good and have the reassurance of the locking ring to keep it in.

Looks good and very good quality
