Stage 1 Cobb Tune Help

[Muhnopoly]

2 questions ! Currently only performance mod would be res/muffler delete and replaced with mid pipe muffler and y pipe. Getting my Cobb AP in a few days along with the gurgle tune by PD tubing. Should I upgrade spark plugs ? Currently at almost 50k miles and don't believe they have been changed unless the dealer did so. Ive been reading a lot of people say to get new gapped spark plugs. But no idea which ones are good.

Also cobb says "cobb CAI" but people say just replace the stock drop in filter and its just as good as getting a new CAI

“Green filter” drop in or K&N and Airaid tube probably the best bet, as far as plugs I use Motorcraft 542 they come gapped .026 -.028 I believe....I would consider changing plugs every 15,000 miles or so a regular maintenance.

yes do plugs, get some pre gapped NGK's from Tune+
