I'm sure the 6th element stuff comes with directions for install. Or just watch a youtube video of someone else installing one. There has to be a couple on there lol. I know if you've never turned a wrench on a car, it can seem all but impossible or cause a bunch of anxiety, but it's actually pretty easy stuff. The 2 things you mention are pretty basic upgrades and are perfect for someone new to get their feet wet. Not sure where you live, but maybe you have an experienced friend close by that can help. You will spend half the cost of the upgrades just to have a shop do them, when both can be done in 30 minutes with simple hand tools. And I guarantee, that if you do the upgrades yourself, the feeling you will get when you are finished, will be better then any other feeling out there. I remember being about 8 years old and successfully putting a new alternator on my moms car. My mom was so proud of me and I was even prouder of myself. The shop wanted like $50 to do it. and that was $50 in 1984 money
