Review on Spectra Premium MZ49 Distributor by Jeff Henkhaus

This distributor changed my ignition timing. The distributor had to be turned all the way up for the car to even start. I consulted two other distributors from a local auto parts store to try and figure out the problem and this distributor was unable to match the other two distributors' ignition timing. Two other distributors from different manufacturers (an OEM and a Duralast) can adjust the ignition timing to 10 degrees with very little twist.
