COVID-19 Update: Our website offers seamless ordering anytime, and with the exception of business critical personnel, the majority of our customer service, call center sales staff marketing and related support are officially connected and working from home as of Monday, March 30, 2020. Like most fulfillment centers, you’ll likely experience some delays in shipping, as our Warehouse team is running at reduced capacity. We are continuing to take extra precautions with additional cleaning and sanitization in our fulfillment center. With the new government guidelines in place, we hope to be back to normal sometime in May. For additional details, click here. Show More… Show Less…

With their reduced bolt head size, it's a lot easier to tighten-up your intake manifold when using ARP intake manifold bolts. Instead of a 9/16"-bolt head size, these ARP bolts use a 3/8" size bolt head, which allows you to use a smaller wrench and get in those tight spots to snug up the bolts.
