It depends upon one's perspective, or, at least, if one plans on participating in car shows and keeping to original. In the latter case, then it's important to have the original style six cell battery if that was the original equipment, original style hose clamps, shock absorber tags, and so forth.
Others are content to use OEM parts. Obviously, if one has been using an early Road Runner as a daily driver and buying Mopar batteries every few years, it's not going to have a six cell battery any longer.
Others just use specified parts, as in a Wix filter or a K&N drop in is fine, but a cold air intake isn't. I admire all three camps, but probably fall into the latter two categories. I'll buy a lot of stuff from the dealer, if it's reasonable. My F-150 has a lot more Motorcraft parts on it than one would expect. However, I have no problems with using a Wix filter or KYB shocks.
Europe can be a bit different, I suppose. When I had the old Audi, just about everything I used was an OEM type part, including filters. Worldpac's retail distribution network here made brands like Mann, Mahle, Sachs, Hengst, Graf, Febi, Bosch, and Conti very affordable and readily available.
