K&N 56-1390 Custom Racing Assembly Product Reviews

Thursday, May 3, 2018 - Part 56-1390
A good addition to vintage 1979 Allegro 1300....makes for a good throaty roar from air induction and once mixture reset some precious extra horses for acceleration and hill climbing...Not only that but looks pretty cool in engine bay and will not have to worry about getting paper elements for years to come...Comes highly recommended by David Vizard in his yellow bible Tuning the A Series Engine and the words of the guru are truly gospel. That coming from a tight fisted cynical Scotsman is high praise indeed.

I ordered the wrong part first. Exchanged for the correct one. Customer service woman on phone was very nice. I like the correct parts. Just what I wanted.
