i no i posted something about this before but i cant find the thread. but once again my 05 silverado is in need of a tune up and im asking you guys help with the parts i need. im just wondering whats the best spark plugs,oil filter, and anything else i might need to change. i use to get 20 mpg but i dropped to barely getting 18 over time. she has 93xxx miles on her so i know shes not brand new. i do have a k&n intake and aftermarket exhaust. any help will be appreciated guys
NGK tr55 plugs.Originally Posted by boudreauxcody@hotmail.com
I like mobile or castrol gtx on the oil and filter. Or just a reg fram. Also get a new air filter. K&N drop ins are nice because they are washable, and flow much better than the stocker. It also would not hurt to replace the spark plug wires. Stock replacements are fine, MSD are the best IMO aftermarket.

+1 on everything above, and also maybe some lucas injector cleaner. I changed my plugs to the tr-55's and started using 91-octane, and notice about 1.5 almost 2 miles a gallon intown

No not the iridium's... those are $$$ the tr55 are probably the most commonly used by NA ls motors.
Well i need some knew ones cause these E3's are not lasting long and i think they misfire some

You should also clean your MAF wires with some CRC MAF cleaner spray and your throttle body with some SeaFoam Deep Creep. You'd be surprised how much these two little details will pep things up if you haven't done them in a while (or ever).
Then run a single can of regular SeaFoam in your next gas tank fill-up (I do this every 5-6 tanks), a third of another can in a top-end cleaning through your brake booster vacuum line (wait 20 minutes and then start your engine), and the remainder of that second can in your oil (and drive for a few miles before your next oil change).
