Buicks aren't made to go fast. You're fighting an uphill battle.How can I make my 2002 Buick Century Custom faster?You could try replacing those AC Delco Platinum plugs with autolite XP plugs. Make sure the intake is not leaking (1996-2003 3.4L and 2000-2003 3.1LV6's are known for leaking intakes). Another thing that may help, but the car will be down for a while, remove both heads and have them slightly milled or "straighten" the section that mates with the block due to warpage.How can I make my 2002 Buick Century Custom faster?Tune-up and a fuel filter
