Napa know how....
Napa is generally the same cheap china **** you can buy anywhere else, but marked up a BUNCH. Just bought a cap and rotor for a tbi 350 chevy, from the local napa store, was supposedly "Delphi" brand. Shop cost was nearly 60 bucks, the cap was a peice of crap, aluminum terminals, some of which were pressed in crooked, rotor had zero identification markings. Went to rock auto, got a NGK branded setup. It was 1/3 the price, even paying shipping. Brass terminals, very nice parts. Napa was better quality than most 20 years ago, but now its china **** at a 90% markup.
