Product Details

Holley 125-1005 Single-Stage Power Valve

There still seems to be a lot of misconception about Holley carburetors blowing power valves. Nothing could be further from the truth. Holley performance carburetors built since 1992 have utilized a power valve check system that effectively eliminated this infrequent problem. Consisting of a spring, brass seat and check ball, the check ball system is 100 percent effective protecting the power valve diaphragm from damage due to engine backfire.The power valve check ball is designed to be normally open but quickly seals to close off the internal vacuum passage when a backfire occurs. Once closed, the check valve interrupts the pressure wave generated by the backfire, thus protecting the power valve diaphragm. There is no way that the power valves diaphragm can rupture due to an engine backfire!

Autoplicity had the best price by far on the item I was looking for. I paid for 2nd day air shipping and my order total was still less expensive than ordering from any other merchant. My item arrived the day after I ordered it. I will definitely buy from them in the future.

Best price fast shipping. will deffinitly order again

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Best price on the Internet and quick shipping

Very fast and easy ordering system. My order was shipped the next day.

Just placed the order even after reading some scary complaints about this place.

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.
