Performance filters with cold air intake - K&N:
An air intake revision needs to be much more then a performance filter with a cold air intake. It has to be designed in conjunction with the engine application and not just be thrown together from the parts bin ala K&N.
Spark plugs - Iridium:
Iridium are a 'double sided sword'. They are not better than other types of spark plugs. I generally stay clear of them even in racing applications.
Free flow exhaust:
With an exhaust design you have to first decide whether you want to go for torque or peak power. Then you have to decide, whether you keep the stock cams or go for different cam characteristics. Then you calculate and build. FFE is a totally wrong interpreted idea. It is not just a bigger bent pipe with some silencers. To get the most out of it it needs section welding and purging, the Y-junctions must be of a certain angle, the leading edge being clean, the diameters and lengths of primaries and secondaries calculated correctly, the collector diameter correct, the pipe getting reduced in diameter towards the end, the bends the correct shapes etc.
To build a proper exhaust is an art work.
Whether a high quality oil is synthetic, semi sunthetic or mineral has got no influence on performance.
