1500cc - Silverado 1500, Sierra 1500

My Silverado had been running rough for months, but these injectors smoothed everything out on the first drive. The plug-and-play fit on my 5.3L made the swap take less than an hour.

These injectors woke my tired old 4.8L up instantly—no more stumbling at idle. The matched set saved me from chasing a single bad one, and the 1500cc flow handles my mild cam just fine.

My 2007 Silverado 5.3L had a rough start and misfire before swapping these in, and the matched set of 8 made the install straightforward. The 1500cc flow cleaned up the idle and brought back smooth power across the whole range.
