You're spark plug terminal ends do not have sufficient clamping ability, the clamping sides are to short, these are probably better suited for 7mm wire rather than 8.5mm. I had two spark plug terminals pull off the wire as I was trying to remove from the spark plug during a fitting/cutting procedure for my new engine. I've since replaced all 8 plug ends with better quality MSD-34604 terminals. See attached photos. I recommend you investigate better quality terminals that more securely clamp 8.5mm wire. The terminals you use are junk. I just purchased the TSP 8.5MM UNIVERSAL SPARK PLUG WIRE SET WITH 135° PLUG BOOTS, BLACK, SKU 85035, last week. Apparently you get what you pay for...

Great service! Had a small problem with a product they addressed it immediately and professionally! just want to say thanks guys!

I ordered 8-Cylinder Male Pro Billet & Ready to Run Cap & Rotor $15 received it, didn't fit my distributor, I asked to return, yes but credit for cap only, I would pay return shipping no problem but I only get credit for Cap no shipping to me! Now I would have lost $27 for a $15 cap. It will be on my shelf for reminder not to buy from TSP!

Ordered rod bolts and then wanted to cancel the order because they will deform rod and need machined and description says nothing about it. Sent 2 emails and they never responded and still shipped the order.

I just seen one of your “egr block off plates” on a c4 corvette, wow , just wow , there is a gap and it looks like straight dog water. Y’all can do better than that. Wow
