I'm looking to join the UEL header club but I'm not a huge car guy so wanted to see if anyone had some advice. I currently daily about 30 miles to work and I live in the Cali desert with summer temps up in the 100s, so my current plan is:

- JDL Headers

- Flex Fuel kit

- DT Stage 2 tune

- IKH24 spark plugs

- an air/oil seperator

Is there anything else I should consider getting? I have previously changed my exhaust by myself so I feel like I can probably figure out most things. Is there anything I shouldn't try doing myself? Any other general advice?
